Frustration is an spectrum that is true, but it would be safe to say many people who spend a considerable time of their life in gambling will face frustration at some point of their journey, because losses are inevitable when one goes into gambling in the long term.
One does not need accurate data on people and their feelings of frustration to realize the mixture of expectation and gambling will always end up with frustration and bad feelings, against the casino and oneself (for losing whatever amount of money).
I have found myself to feel frustrated during some gambling sessions and I am sure it has also been your case.
But when someone experiences frustration and can stop it is good because they will be able to stop what has made them lose lot of money, it just that people who feel frustrated eventually also remain in the gambling environment, they bet again and deposit money again even though they know that previously they had lost lot of money that they felt.
Moreover, not everyone who has known gambling for long time will be able to realize and follow up on what to do when in certain conditions, humans always have unstable mindsets and feelings.
Yes, but the problem is that often this awareness is very rare, meaning that even if they manage to restrain themselves and stop at the right time, at a different time the difficulty will occur again, which in the end there is still a big possibility for them to always stop when they have lost all their money at that time. A gambler who makes the same mistake again, in my opinion, is a gambler who is far from being responsible, which is most likely because they have a wrong understanding of gambling, I am sure that they only focus on their winnings but do not think about the consequences of this activity and that is the reason why they always make the same mistake again even though they have previously experienced various bad things due to such actions, so in this situation I think the main thing that must be corrected is understanding and responsibility.
