How many transactions can you ran per second on major coins like BTC?

Depends on what you mean, if using batching technologies like Lightning Network it is theoretically unlimited.

If you mean on the globally replicated and stored forever blockchain, I think it's 50/s or something like that.

I keep hearing those marvels about how lightning network solves everything and gives everyone a pony, but it is currently estimated to perform about 200k transactions per day.

Pix achieves literally a thousand times that.
