I think it starts with money management. For example, if someone doesn't know how to judiciously manage their bankroll or the money in their banks account, even if they are spending just 1 hour at the casino, it's very possible that they can spend a very huge amount, meanwhile someone that has spent even 3 hours might not have gambled off the amount they that lasted just for 1 hour has already spent thousands of dollars. I might be gambling for 3 hours and just spend $200, while someone that is just starting has already lost $2k or more, there situations like that.
You're right, on a personal level , each of the movements made in the game is independent of each person, Because the money belongs to each person and each person decides how to spend their money What can be said is that this serves as an example for those who have money to Know how to use it when they go to play there's nothing Better than making a good plan to manage the money to play with before playing.
