I think yes. somewhere out there girls also gambling, but she never show herself because a woman in gambling is a taboo thing. Especially on some country, if women do gambling, she will do it secretly.
Yes they do, actually nowadays they are not hiding anymore, besides sometimes it is an advantage to them if they show that they are a woman,sad to say some guys also make a nick that is a girl, which results to stereotyping and pointing at a woman player as scammer...
