I was quite doubtful he was building a business with the money he got, but indeed nothing is impossible if he really can succeed in building a business with money, but usually people who have gotten easy money will be difficult to get out of the gambling ease zone.
If he could realize what he could do with the money. But if not, who knows what he will do with the money? After all, that's just an approximation since I don't know anything about him either. But usually, if someone earns a lot of money from gambling, the money will run out quickly because that person will use the money to buy things that he doesn't have or use it on things that are not necessary until the money runs out. And when the money is gone, they will return to gambling and hope to win big money like before. This has happened many times around me and for people who win money from gambling, their lives never change.
