yes i can say its more of a guy thing. one of the reasons why i think its so is because of the financially responsibilities that the men do shoulder and also that men always want to earn more so its pretty easy as a guy to get involved and also if you have friends that are into it then it will be more easier. but i think things are changing and have seen some ladies go into gambling although the percentage is still kind of low but maybe in some years to come we will have a good population of them especially for those who wants to do it for fun.
Guys have more affinity for gambling so it may be regarded as guys thing, but at the end of it all, not all those that are gambling are guys alone, it's all compromise a combination and there's nothing we can do about it, we often believe that men also have more higher ability to raise financial responsibilities unlike the way it was being common with women to be dependents on this, just as you have also given, women have a very low interest on gambling activities and this is common everywhere when it's all about gambling.
