I don't use FTX exchange, I use Binance instead.
Let's suppose you have funds on FTX, now that you are unable to withdraw, will you halt gambling for the time being and how will you survive this time?
Honestly, I do not think FTX will have an effect on the gambling industry except for your given example of funds being frozen on the FTX exchange. And I do not think that it will hinder me from gambling as long as I have funds in my other wallet. So in short, as long as I have funds, I don't care what will happen to FTX and I will continue to do my gambling activities.
