This is very true in slot machines as in order to get the money back you need to play again and again and hoping for that max win.The bad thing is that a max win with an optimistic prediction happens usually once in 2-3 years if you are very lucky but it also may never come for quite some more years and while a person is back chasing it this means it will constantly lose money and he will lose it all,he will not make a distinction between reality and his desire to make the money back by playing slots,this is where addiction starts and needs to be cured.
In sport betting is a bit easier as if you have enough patience to wait for the games you have bet on then most likely addiction can be controlled.
I’ve never trusted slot machines, I’m almost sure that there are algorithms that calculate winnings in such a way that the player will only lose, and it’s clear that the casino has the opportunity to put everything in its favor. In betting, a player definitely has more chances, but this is only if the player is good enough at it. It is difficult to compare machines and bets, because in my understanding they are too different types of gambling. If you rely only on luck, then there will be losses in all cases. If you take your knowledge as a basis, then the best result can be achieved in bets, where you can independently determine the winner.
