Am I correct in thinking that, when mining bitcoin, only one miner in the world will gain bitcoin from verifying each block in the blockchain? How could this realistically make anyone a profit?

As I understand it, the hard part of mining bitcoin isn't in verifying the transaction, it's in being the first to find the hash equal to or lower than the target hash. If there are millions of miners all over the world looking for that hash, including giant, multiple-building farms, and only one block is added to the blockchain every 10 minutes, how could anyone mining from home hope to make any profit at all? Would you not just be losing stupendous amounts of money on gear and electricity and always be losing the 'hash race' to someone out there with a more powerful computer? I know and appreciate that people do this purely as a hobby and not always to make money, but I can't see how you could ever make money at all when competing with factory-sized water-cooled farms in China. I presume there's some key point I'm missing that will make everything instantly clear but I can't find it in any other explanation.
Also (side question) if it is true that in order to solve the numerical problem you need to find the hash lower than or equal to the target hash, and there's no extra reward for being the closest, only for being the first, why would you not just guess the lowest possible hash every time?
thank y'all

Blockchain, the amazing solution for almost nothing

In “The Bitcoin Standard” Ammous compares bitcoin to the Rai stones from the island of Yap. Years ago one of the stones fell into the ocean but still was recognized as money because everyone agreed that it must still be there. Bitcoin is like that Rai stone but the blockchain allows us to verify it!

with electrum, what are my options if one day i decide that i want to sync and verify the whole blockchain by myself? i believe one way is to run an electrum server, but i also heard about people using bitcoin core and electrum together, what is that about? what are the differences?

for same purpose, at first i wanted to create my wallet with bitcoin core and them manage it with lightweight wallet, i asked about this on bitcoin and got many of my questions answered: https://www.reddit.com/Bitcoin/comments/ctwsxq/if_i_use_bitcoin_core_to_create_a_wallet_without/
but now what if i create the wallet with electrum and latter decide that i want to run a full node?

Correcting r/bitcoin's misinformation: I just fully verified the entire ethereum blockchain on a 2+ years old desktop and it only took 25 hours (full log included)

In a recent bitcoin's thread thieflar claims that with 'a very nice machine' he was unable to finish validation of the ethereum blockchain and that the near impossibility of it is apparently an accepted fact even among ethereum's developers:
The developers of Ethereum know that this is an issue, they are fully aware that their network relies on trust at this point, and they don't even try to deny it.
nullc comments with:
without being able to count on nodes verifying the history even ethereum seems unable to make a proposal complex enough to hide its insecurity.
I tested the truth of these statements - the result: full block-per-block syncing completed in 25 hours 25 minutes.
Software: Parity at commit 2586eaef929cadcd5ebccdf2d484f1cf6bb14917, compiled with "target-cpu=native", performance options: --tracing off --cache-size 4096 Ubuntu 16.04
Hardware: i7-6700K, 16GB ram, Samsung 850 EVO 256GB. Not bad but definitely not 'very nice' either.
To remove the network speed from the performance equation I downloaded the bare blockchain separately and synced the node from disk. As it's only 20GB at the moment there would be no noticeable difference. 23k most recent blocks were downloaded after that.
The fully synced node with all historical blocks + recent state (ie. exactly like a full bitcoin node) uses 44.3GB.
Parity log.
Syncing from disk: 2017-12-30 20:15:50 Import completed in 87903 seconds, 4803128 blocks, 54 blk/s, 112578528 transactions, 1280 tx/s, 5273835 Mgas, 59 Mgas/s
Downloading the tip: 2017-12-30 20:33:53 Syncing #4803139 d21c…7352 0 blk/s 115 tx/s 5 Mgas/s 0+ 19 Qed #4803162 5/25 peers 365 KiB chain 72 MiB db 2 MiB queue 898 KiB sync RPC: 0 conn, 0 req/s, 0 µs ... 2017-12-30 21:33:43 Syncing #4825928 b3cb…6ec9 4 blk/s 720 tx/s 29 Mgas/s 0+ 15 Qed #4825945 7/25 peers 305 MiB chain 609 MiB db 3 MiB queue 3 MiB sync RPC: 0 conn, 0 req/s, 0 µs
Conclusion: any pc that can run a modern game can easily fully sync (no state snapshot downloading, only blocks) and run a full ethereum node.
edit: apparently reddit immediately deletes posts with links to mega
