Gambling has absolutely no element of certainty whatsoever that can guarantee you a win at the end of the session, it will never be known unless you have completed the game which means that your excessive actions with the aim of getting a big win will actually only make you feel more disappointed, that's for sure, because you put excessive hopes in a place that has absolutely no certainty. On the other hand it seems that your statement is reversed my friend, there is absolutely no pleasure in the situation of addiction, and you have also said above that they will only suffer a lot of problems as a result of wrong gambling, there is no pleasure at all in the defeat that dominates.
What you say is true, victory in gambling cannot be guaranteed even though we have tried to pursue it and if we still want to pursue victory until the end of the game session then all we have to do is regret the wrong actions we have taken.
Yes, someone who is addicted at the start of the game will feel pleasure if he can gamble continuously, but in the end he will feel that this pleasure will be the beginning of destruction in his life because he has lost a lot. money due to gambling without good control.
