Where does the money come from?

[Kurn, son of Mogh]

With the exception of the highest levels of poker, the vast majority of winning poker players' profit comes from the bad play of their opponents rather than from their own brilliance.

That's why the single most important skill in poker is game selection. It does you no good to be the 10th best player in the world if the 9 who are better than you are sitting in the game.

That has precisely zero to do with gender, though live, being female may make some men make faulty assumptions. Of course that is also an example of a mistake from which you profit.
