Not just in gambling but also in other aspects of life, men usually take more risks. Maybe it’s simply in our nature, we love thrill, adventure, and taking risks. So, it’s not surprising that men also take more risks in gambling and tend to be more short tempered as well. The number of female gamblers is increasing, but men still outnumber them. There’s no exact data yet on the ratio of male to female gamblers, but I believe men have the greater number. Like I said, it’s in our nature, and that alone explains it.
Though we have no concrete data on this, but as we have seen, male gamblers dominate the female gamblers for so many reasons. For one, females have more responsibilities at home that they don't have time for other recreational activities such as gambling. Aside from that, they are usually taking care of the budget of the family. So she knows if there's extra or not. On the other hand, males have different approach on this habit because they have more time so to speak. It is not males have less responsibilities but that's what it seems in most cases.
