It's a sad situation. In the past, I also had my account blocked on a certain exchange because I had made a direct deposit from a casino to my exchange account, and support informed me that this was not allowed. However, they quickly unblocked my account, and I was able to make withdrawals and deposits normally, as long as I always withdrew from the casino to my wallet and from my wallet to the exchange. This was explained to me by support.
But in the case of the exchange you used, I checked their Terms of Service and there's no point prohibiting deposits from gambling sites. Therefore, they are intentionally stealing from you. When I researched this exchange, I was shocked.
On August 6, 2023, they had their first scam accusation. Just imagine, that was 3 years ago!

One year passed without any fraud accusations against them, but:
- October 2024: 3 accusations
- November 2024: 5 accusations
- December 2024: 1 accusation
- January 2025: 1 accusation
- Every month of 2025: accusations of fraud against them
- This year: They continued with the same modus operandi and received fraud accusations
