When your mindset about gambling is just for entertainment, you can’t really expect to win.. just my observation. Because when I’m not serious about it, like when I treat it lightly especially in sports betting, I don’t study the games before placing bets. I usually end up losing more. I don’t lose big, but if you look at the record, it’s not profitable or even close to break-even.
But when I start believing that I can actually be profitable, that’s when I do the work. I study the games before betting, and that’s when I start getting better results.
Seeing gambling as an entertainment does not equal losing bets, part of the entertainment in gambling is winning too. It's just that they consider winning as a bonus, not a priority. Also, people who see gambling as entertainment do not take it as seriously as a gambler who only gambles to make a profit, but they can be serious enough that they still want to win.
