Coming back the next day is simply continuing a random series of events.
Nothing changes in the probabilities when a day passes. Or a year. Or a lifetime.
The odds are always the same. And the chances of winning for the gambler are always lower than the house.
Yes, it is true that the probability will remain the same, but that is also okay because they will never think about the probability. They just want to keep playing slots and try to win a few dollars, and if they are really lucky, they can win a lot of money, at least more than the amount they have already won.
And gamblers also know their chances of winning will not be greater than the house. They will also not stop playing slots because they have found pleasure in playing slots. And when they become addicted to playing slots, they won't think about other things because it's not important to them anymore.
Slots are probably the gambling where the house edge is the largest. Many of them do provide provably fair formula and I've never gave it a good look but from the mere work of experiment through playing, it has much lower probability of win on comparison to other gambling options.
The prime reason why I play slots is they are fun. Specially the animations, the animations makes me try new slots and come back to ones. It's due to the animations that it feels a small amount of your money is working for a long time. Slots is all about the graphics. Whenever I play slots, I hope I last for a long time rather than withdraw my earnings.
