모든 상금을 최대로 줄였습니다. 인출 가능 금액

Having all winnings reduced to a max. withdrawable amount 

Hello, could you please elaborate a bit more ? Did you win more than you could have withdrawn in the casino in a certain period of time and therefore your winnings were taken away ? What casino are you referring to please ? 

Let me know so I can get a better overview of the situation.
