That's with slots and casino games only. When it comes to poker, it's a must to pursue a win. If it's a tournament, then aim for the top to get the grand prize, which is mostly 5-6 digits in USD. The same with sports betting, always aim for a win, and do every analysis as much as possible to increase the chance of winning. That can never happen in slots. It's always a blind bet.
Anyway, playing those types of games will require a gambler to move on very quickly after losses so that he won't be chasing losses. That's why it is crucial for slot players to forget a loss as soon as the deposit is gone. This way, we might save some of the money in our savings.
I agree that the playing style in poker is very different from how gamblers play slots and other casino games.
In a poker tournament, you always need to calculate your moves, and at times, you have to be patient and hold back, especially during the crucial stages of the tournament.
