So my question now is who are the people that mine Bitcoin if the profit will only be negative?

I don't think there's someone who will mine BTC with a negative profit unless you are willing to contribute to the network some people use USB miner(Compac F) just for lottery and the power cost of running this for a month is around $1-2 it won't hurt your pocket compared to big units like s21 mention above.

Or people who mine BTC are those who live with a pretty cheap electricity rate I think around $0.06 cents or less should be profitable and breakeven 2 to 3 years for a sample Antminer s21 pro with the current Bitmain price around $6,300.

Xrp or trx is a coin I'm really interested in. Do you think mining these coins will be profitable or just the same as Bitcoin?

I don't think you can mine these coins you can only get rewarded from those coins through staking not mining.
There are still other coins to mine if you are looking for profitable then check this one for ASIC units https://www.asicminervalue.com/
GPU mining is currently not profitable so I can't suggest building a mining rig.
