Probably, for most gamblers who are not addicted, this is not even a trick or strategy, but a standard behavior. In general, using this example, you can see the difference between a healthy person and a patient with gambling addiction. If a person is constantly losing and has lost the entire bankroll, it does not mean that he is addicted. If a person wins (that is, he has achieved his goal) and, nevertheless, continues to play, then, as in the first case, he loses everything, then this person is addicted.
Indeed you're correct, apparently it's not every gambler that's supposed to be driven and wired negatively.The efforts of a gambler against addiction is earned from cautioness and early stages of awareness & self exclusion.
