First of all in your narrative because it seems very unusual in your country for women to gamble in public but I guess in places like the US women are allowed and treated the same to gamble because you will see lots of women. in a physical casino even with a few bottles of good beer to relieve the tension and anxiety involved in the game.
And secondly in my opinion no one can confirm how women are treated with regards to gambling in my area because I haven't paid much attention to this topic, but there are no restrictions on women who gamble in my environment.
Maybe some people always or often experience that, when a beautiful woman wants to bet at say in a game of roulette and the table is full, you will give the man and woman themselves space so he can bet. So with that said, I'd say it's normal to give way.
