I think the problem is that gambling is mostly overrated and over hyped, which makes a lot people have high hopes and expectations from gambling whenever they are gambling. Yes you are right, how one choose to approach gambling matters a lot and plays a very vital role on how they cope with it. The same gambling that's a big problem to others can also be a source of excitement and recreation to another, it all depends on the gambler's approach and expectations.
I think gambling without expecting to win is quite wise, because every win is always acceptable to all gamblers. But if you see gamblers who are able to accept losses more wisely, they are gamblers who have a different approach and assessment of gambling. Because not all gamblers can accept losses, especially those who expect to win every time they gamble.
It is true that you will never be satisfied with gambling but you should use your own criteria on how to control your satisfaction level. You will lose most of the time this may not be a good idea but real gambling platforms are so cruel. Between continuing to play and hoping to win I give priority to having fun which may be considered a trade off but the level of experience should be gradually increased to increase the expectation of winning. But I bet expecting to win like most sports predictions through review and research.
