I don't think everyone looses, but there is a large percentage probably do. But professional Poker players do exist, so there is a small percent that can make it work.
Sadly I'm one of he larger population that has only lost money.

I would advise you quit gambling. Unless you're good at poker, you are only going to loose money.
If poker gives high quality entertainment for only few lost dollars or so, is it bad? Consider that there can be days where u win. Especially, if u playing with ur IRL friends

Concerts' tickets and so on cost way way more money.
