I think it's about the nature of men. Men are not biologically wired like men. There are things women love to do, and there are things men also love to do. Of course, what might be fun for men may not be entertaining for the women folk and vice versa. So I think me are more of risk takers, while women are less of that. It doesn't mean that there are not women who takes risks, nope, they do, but few.
Gambling involves risks and money, men acb go all in wishing for something great or also a loss if it happens l, but I don't think a woman would readily stick out her money in such risk all in the name of betting.
Things have changed now, women and men loves almost the same thing in fact women loves a lot of what men are doing even in wears you will see them buying it and it will fit them very well but as a man you cannot do that because it will be abnormal in the eyes of people, so is in the old days you can see them liking and having different things that you would see and no that only women can have this, the same with men so actually in gambling a lot of them also like the same thing, is not only the men that wants this rich because we women also do so anything that men do to get money whether regular or ones in a while they would also be there.
