-A man who is known to be a gambler may still be considered for marriage by a woman, but if a woman is known to be compulsive gambler before marriage, most men will run from them or not even get close enough to consider them for marriage.
Why the bias? should gambling be only for Men?
Unfortunately this is normal all around the world. People see women as stable protectors of home and bearer of children, which is why people often criticize women for things men do on daily basis. As an example I'll give you a man who often changes women and every week goes out with someone else is seen as someone popular, who knows how to pick up girls, a hustler. A woman doing the same thing will be called a slut. People will speculate that she's probably getting paid for it and so on. That's why a woman gambler will always be criticized more than a man.
