To have fun, of course, gamblers choose games, not sports betting, because in sports betting, the average gambler will expect victory or profit, not just fun.
All types of gambling for some people are only considered a place to have fun, even if it's sports betting.
Look at your experience, some people laugh and have fun in every bet, even though they lose, they still enjoy the bet.
For example, a gambler streamer sees their losses in all types of bets, but he still laughs at his defeat.
Either I don't understand the aspect of gambling or you may have a little experience in gambling.
I think you understand and understand what I mean by choosing a game as a means of betting and looking for fun.
From my experience a game provided by the casino gives enough pleasure when I play it and I bet on sports betting as a place to get an advantage because in sports betting I can do research and make predictions so that I have a bigger winning percentage in sports betting even though the advantage is only small because usually the winning team will have quite low odds.
