There is a chance that the nature of the game has something to do with the gender that plays in that game most. There is no official study for this yet, but I am thinking that we will find more females playing and drawn to luck-based games than skill-based games because of how difficult the process of learning skill-based games may be.
Another observation about luck-based games that a new gambler with an interest in them has to know is that they have the potential to make you, as a gambler, spend more money gambling than skill-based games.
What do you think?
I have observed this too it is very hard to find females that play skill based games due to the fact that it requires some learning process and a lot of patience which they don't have, females naturally are all about making it fast and they don't like engaging in things that might be difficult or stressful to them. Luck cannot always be relied on and like you said they make you spend more because you might have to make multiple trials if you are unlucky, But whether you are into luck based games or skilled based games you must learn to take responsible risks
