That's to tell you how well women are now involving in gambling and as time passes there's a tendency for more women to indulge in it as well, since the social media have made gambling more popular and the fact that it involves sporting activities makes that more possible.
The major reason why it's rare to find women gambling is because of religious beliefs and societal practices. Women found gambling are said to be irresponsible and aren't meant to be wife's. The society might discriminate them and avoid them in so many socal gatherings. But then things have changed in the past years gambling is not longer a thing you have to do in the public as we now have online gambling platforms. You can gamble from any where without even letting outsiders know you gamble. The rate at which women move into gambling would have increased due to such reasons compared to the past.
After all, there are also many women who are involved in promoting gambling and thus, I think it is a sign that many women in this era have become gamblers. Not only that, because in this era there also seems to be a lot of women who do activities or whatever that men usually do or do, but in this era women also do it. Perhaps, due to the impact of gender equality or things like economic needs and many other factors that make women also do not hesitate to gamble on various online gambling platforms that are increasingly easy to access.
