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.
something big is obtained instantly or very easily, it will also run out very quickly. I mean when a gambler gets a big win after that the money runs out quickly and its unclear to buy things or anything. because its true what @bangjoe said that something easy will make someone comfortable and its difficult to get out of the convenience zone. buy whatever he wants because later he will still win again from gambling without realizing that such luck will only get once in a lifetime.
for me, only professional gamblers who can manage their winnings from gambling well can have a realistic mindset and have the thought of always doubling their money in places that are not too high-risk, for example opening a food business.
