I agree with what you said because after all, the bookie is the real winner and we must realize that even if we win, it does not mean that we have won from the bookie but we have only won from other gamblers who have bad luck because regardless of whether we lose or win in gambling, the bookie will still make a profit because this is their business and we as players are only a driving force to keep their business running.
Don't be too naive and heartened when we manage to win because it won't have any effect on those gambling bookies who always profit in every movement (gambling) that we do.
Addiction occurs sometimes because we are too confident that in the end we can beat the bookie which when the reality does not match our wishful thinking, it will make us too obsessed with the gambling that is done so that we forget the responsibilities or things that we have to take care of in gambling just because we are fixated on the thought that we will win from the bookie.
Winning is an expected thing but that does not mean we can get a win from the bookies because in the end something like this is clearly a mistake where the bookies will continue to win in every action we take in gambling.
