However, we do not know the exact number of women who gamble. We cannot predict whether the number will not be as many men who play gambling or whether there are already similarities in numbers between men and women.
It depends on the offline casino or online casino because if you look at the offline casino we can see it firsthand with our own eyes and it's definitely filled with men because it's rare to see women there except as entertainers, but maybe we can find bigger statistics on online casino, it's just that statistical data is not published by the casino.
But I'm sure there are lots of female gamblers in online casinos because some of my office friends often play slot gambling on their cellphones, but I don't know for sure whether they really have a lot of users, because slot machines just need luck and don't need a mathematical strategy, so in my opinion Online casinos are more popular with women too.
