You are right, same as the other user, but this is if and when addiction is already involved. That is, if the gambler is an addict who after losing some significant amount of money to gambling, decided to quit but is still hanging around gamblers, then I would say that such a person isn't ready at all.
Said this because I myself I've had an experience in 2022 when I lost almost $3000, my entire life savings to betting, it was a very devastating period for me, I had a lot gambling friends at the time and people I cannot go a day without (or so I think), but still, I never gambled or placed any bet for over 1 year after that loss even though I still hand out with my gambling friends both online and offline..
Losing big money in gambling is like a trap, which is that the more you lose, the more you are ready to bet to win back. If it reaches the point where you have to borrow to pay off previous debts, then this is already a critical situation, in which stopping is a mandatory condition for getting out of this situation. The most important thing to remember is that there are no unsolved situations in life, and the sooner the player decides to take this break, the easier it will be to think about the situation and find ways to solve it.
