I would definatively withdraw the vast majority of the winnings and use it to invest in something like a house, bitcoin or stocks.
Statistics are not in your favor, so if you win big, don't push it but take the winnings and use it to your advantage.
i will also buy a house and lot so that i could have a remembrance from my winnings.
Unless you won the lottery or something close to that I doubt we could win enough in a casino to buy a house and if you do, then you are probably in a reasonable economic position already that does not require for you to earn any price in any casino.
