Most folks do go all out in gambling when they are frustrated most times , due to some certain losses and the mindset of always trying to get back their losses back by gambling or staking huge amounts of money that’s why gambling is not for the weak as folks usually say because if you don’t have good self control you only messed yourself up .
I wouldn't go as far as saying "most people", because i don't think there's any data on that. And i don't even know if it's possible to get accurate data from that, because being "frustrated" is a spectrum.
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.
