You can't win against an RNG. You will eventually lose and your loss is likely to be much bigger if you don't start with the right expectation.
Did they expect to beat the RNG? That's why it called RANDOM in the first place right? What they are expecting is not to beat the RNG but somehow hit the right algorithm even a small chance.
Sometimes the strategy is not just beating the house since obviously it's not likely to happen. The strategy is how to managed properly the bankroll.
And you know, it's not making sense to just post a DON'T GAMBLE AT ALL awareness here. Every gambler knows that losing is always there. They know they are taking chances. Even those newbies already know this. It's just the matter of how they will handle it once they lose - will end up crying or move on.
