This is a way to advertise the platform that pays him on this is I will not be surprised because he has great influence in making people see another way of making money with gambling. Know his followers now will start watching this anf thinking of going into gambling so they can win this kind of money even though they don't have the skill ana courage to put things in the correct order.
IIRC, it's been said how much or the estimated amount that he's getting paid for it. At first, it became a controversy and many became curious if he's really advertising it or if it's just a coincidence that he's played there and won that much.
His influence is great and that's why he's got this sponsorship from them and we might see the same strategy from other casinos and exchanges that will hire celebrities for being their ambassadors.
