Is it based only on your own observation or do you have any data source for this?
I suspect this is true, but I'm curious on what the actual female participation % figure is.
There could be a few reasons for that. Women are more risk averse in general, but, at the same time, are keen to participate in activities that are considered socially acceptable. So when gambling became more popular, i.e. due to mobile apps etc, more women have decided to give it a try.
so I did a quick search on Google and I found an article with a title "male vs female gambling statistics in 2024" you might find it Interesting(because I did)but I am not sure if it is exactly what you are looking for.
Here's the link to the article
Fascinating Male Vs. Female Gambling Statistics in 2024 You did a good job in taking your time to make this research dear and from the link you dropped, yes the number of male is more than that of females over the years and I think will continue to be greater for a long while, but we also seen that the number of women getting involved in gambling is gradually increasing and with time the percentage could become even greater than it is currently.
A good number of men out there are more interested in sports based gambling activities not like there are no women who gamble on sports activities as well but majority of us would prefer gambling on casino based games, like card games, slots dice and the rest of them. And I've come to observe that most women who gamble on sports activities are influenced and motivated by the success rate of their male counterparts in gambling.
But their are also some women that are very good at gambling in sporting activities, they analyse sports very well and it helps them to make good predictions just that they're not very much compared to those without those features.
