What is serendipity?
That's luck... When the chance of something happening is extremely small, and yet it happens to someone. Without luck there is no success in gambling, especially when it comes to slots.
I have had a lot of nice and big wins on slots... but I have never hit a really big win, at least nothing extremely big. I didn't win a life-changing amount. But who knows, one thing is clear: Our chances are small, but if we don't try & try then we have no chance.
Though, there seems to be a small difference between just raw luck and this concept called "serendipity", anyone can have some good luck at the casino and be able to withdraw a handful of Satoshis or dollars as a result of a good session. But Serendipity implies the person who is gambling is pretty much at one of the lowest points of their life and with little left to lose, so they turn to gambling as a distraction, usually with little money, a good luck streak occurs and suddenly the person has a life changing amount of money to solve all thwir problems snd difficulties.
It is not the typical person who already had an estable life and managed to get rich, we are talking about people who are desperate for a solution to their problems and by chance gambling provided what they needed.
Though, one must be careful with these kind of experiences, since they are not the norm, but rather the exception.
