Few people have successfully done this before but the question is are they able to move on? Without thinking about gambling ever again? Because so many gamblers find it very hard to quit even after they made a lot of good money.
Now that they have everything, why find it very hard to move on? This is why one need to be careful with gambling, it's too easier to become an addict.
It's very possible to make millions in gambling, but if you don't know how to quit gambling you will pay it all back to the casino, this is the spirit of gambling, you don't actually win until you know when to put a final stop to gambling.
Yes you are right it won't work most people who win large amounts of gambling will not completely stop completely, I'm sure they will come back to gambling again and start spending a few percent of their winnings on gambling again, retiring and stopping gambling is not possible. stop if only because you won big, if you really want to do it you must from deep within your heart want to stop everything completely.
Because if you stop or retire because you get a big win, it definitely won't work. As a small example, my friend feels like he has won and the profits from all his losses have been paid off. In fact, when he gets a big win, according to him, he will start to stop gambling and retire. but after a few weeks later I saw him playing gambling again, then I asked him again why he was gambling again, didn't he win big yesterday, he just said "There is no fun entertainment other than gambling", lol
