I don't waste too much time gambling, maybe I'm someone who gets bored easily, usually I play only 30 minutes and a maximum of 1 hour, I don't last long in gambling, but I once spent almost 3 hours gambling because the game was exciting
That's the point, it depends on the level of excitement and fun one is having while gambling whether they will spend a lot of time on it or will close it down very shortly after starting. I don't gamble for very long myself, mostly because I'm not that lucky and I lose my budget very quickly because I don't play around a lot and make my bets quickly while trying my luck and having some fun, I might play with odds here and there if I'm playing games like dice.
So I believe a person, unless addicted to gambling, wouldn't spend long hours in front of their device playing gambling games and one gets bored after a while if they are not enjoying the game. It mostly gets boring if you keep losing some and then win again and that process continues without much excitement like big wins and stuff.
