Is poker a profession?

[sebbb]

so... "Winning at poker is possible because your opponents play bad."

Why do win from them? Because they play bad? So that means you are better than them, right? Isn't that because you have developped some kind of skills?

If you say there are bad players, then it must mean there are good players, then. And why are those players good? Maybe because they spent months learning and studying the game. Or are you saying it's just luck and there is no skill involved?

Your logic doesn't make sense.

But the answer to the question doesn't really matter. The term "poker pro" is just a useful way to describe someone who makes a living out of the game.
