Of course they do, why should they not gamble its not something that is for men, you as a example have a lot of girls that are professional playing poker these days on pokerstars, I think that is already saying enough.
That's true, and they are not just an ordinary player because they have also proven that they can make money in poker. But in general, most of the gamblers are men and most of the losers as well. Girls do gamble because there's no restriction on gender in gambling and gambling sites love when more people gamble so they will increase their profits.
