Well, he will be making a decent salary worth of profit from just that investment but do not forget that in order to make that much money he also put in over 170 thousand dollars as well. When you put in over 170 thousand dollars into something that is not stable like let's say savings account in a bank that gives you a set amount of rate for savings, you will be getting a decent amount anyway.

There is a chance dude could even lose money, I know we are in a casino and losing money is unlikely possibility since the house edge is on his side so in the long run he will make money, but it doesn't mean that there is no risk for some whale coming up and making him lose some of his money neither. So, that dude put in money that we wouldn't be brave enough to put into something that is slightly risky, he deserves all the money he makes.
