Yes what you said is true regarding what are the possibilities that can happen in these two situations between winning and losing, anything can happen but it all depends on whether they will be able to control themselves and their mindset or not, while we know how the behavior of someone who has entered the addiction phase.
What this means is that in any situation, win or lose, the act of quitting will only be easy for gamblers who are not addicted, because an addicted gambler obviously cannot control themselves so that they can enter the addiction phase, so I would say that quitting when winning or losing is only easy when a gambler is not addicted, or has full control over themselves.
on gambling field. It wont really be that necessary to quit if you are really just that playing gambling for the sake of fun and not for making income because this is where people do usually derailed themselves when it comes to this manner on which you would really be messing up your finances if you would really be that making yourself that delusional towards gambling.
Dont play for making income but rather for entertainment then you would really be that safe on that part.
One of the reasons why the key to survival in gambling activities is to have control or self-control because after all gambling can really make a gambler emotional and lose consciousness which is a situation that can trigger a bigger disaster, which in addition to the results at the end of gambling are always unpredictable and of course however it is natural in an activity that is probable.
The other thing so far is that gambling with the aim of seeking entertainment is indeed much better, or that means that it is the best approach so that we can avoid various bad possibilities, because by having the intention to have fun and not to earn then of course you will not have excessive interest in winning.
