Most old-time gamblers are good at controlling and faking their emotion I don't think it will be an issue at all it's the newbies that will have a hard time proving if they can take a loss, because while you are learning how to gamble you'll also become good at concealing your real emotion
so it will be no problem for old gamblers.
Newbies will have problems unless they are quite rich already and does not matter to them even if they lose out some money in gambling. For the old gamblers, ones who can have a good self-control those will be fine, but ones like who are sort of an addicted and hardly can stay away might still face some issue due to this notice.
