some people might be restricted from their country or state not to gamble as women.
There is no country that prohibits women from gambling while allowing men to gamble. If there is any reason(s) to prohibit women from gambling, there would be reason(s) for preventing men from gambling as well. The reason is that nobody, whether male or female is immune from the negatives of gambling and so self discipline should matter and not gender.
Personal observation shows that most of the people involved in problem gambling are from the male folks. It will not be out of place to make a hasty generalization that female gamblers are more disciplined than male and if this is correct then there is no wrong for a lady to gamble.
