Any habit that is done excessively, will be very difficult to break.
I really understand what you say, your experience is our experience. almost all gamblers, will experience experiences that are almost similar. no matter how small or big the money that has been at stake, if you do not have self control let alone awareness and responsibility. then what will happen, they really will be trapped in their own habits.
If gambling is fun, then make it something fun with money that has been prepared to lose. if someone gets a win, consider it a bonus. Gambling is a fun entertainment activity, but without understanding someone will have trouble if they don't have good control. can have a bad effect, as you said in this thread.
