Gambling is only so addicting if you are winning unless you are just gambling for fun. When i am playing poker i don't care how much i lose or i win because poker is my favorite game.
I think it depends on the playing control on everyone. there are players who play just for fun still he became an addict thinking that gambling is very pleasant and not a matter of spending money on gambling lol
there are also players who dared to stop when in a state wins. because he has little control
