You are thinking of a professional poker player, but not all poker players are professional, so the one that wins on the long run is a guy like Phil Helmut or Daniel Negreanu or Phil Ivey.
No, I'm not just thinking of professionals, and it's something I've explained repeatedly. Twice in this thread. I am not a professional player, I am a regular player, known also as "reg". I earn money playing poker for years, which complements the money I earn with my main job and other sources of income, like the signature campaigns here.
So you don't have to be a pro to make money in poker.
So, if I start gambling poker, I would be terrible at it, and would lose in the long run, but those famous poker players would win, there is a big big difference.
LOL.
Yes, you better not play poker.
