I would have the nerve to say that it should be like that for all of us gamblers. You should play for your entertainment, not for your profit, because trying to gamble for profit is very dangerous. And it's dangerous not because "house always wins" and all that nonsense, but because even if the house edge is close to zero, you still have a good chance to lose. And if try to gamble for profit, you put high amounts of money at stake because otherwise "it wouldn't be worth the time", right? You don't want to play for two hours and win just $2 in the end, right? You want to win at least $50, right? And that's a big mistake that leads to bankruptcy and gambling addiction. What you should want is playing, and if you don't enjoy it, then don't gamble at all.
maybe if it was just for fun it would be better and playing a small budget at casino games is much more fun than thinking about profits because casinos can never be beaten by their customers.
on the one hand, if he really wants to make a profit without spending a lot of time maybe he can bet on sports betting with a little time to analyze make predictions then place bets and wait for the winning results. but still use a small budget without having to be greedy using large amounts with a big profit mindset. it is a negative mindset.
but what he should know is that all this is not a guarantee because in sports betting sometimes there are still surprises that make us lose.
