Furthermore, it says that it is VPN-friendly, meaning that it can be accessed
from any geographical location. Pease someone correct me if I am wrong, I am not sure what happens if a high roller asks for a withdrawal, is it also NO-KYC?
Yes you can accessed it from different locations but make sure you are not a resident from restricted country or else you are violating the casino ToS that might cause your account suspension.
Follow what @Ultegra posted above to read the ToS. You may still asked with KYC for some reason that is related to your account security such as when you show irregularities on your gambling activities.
It’s an anonymous casino if you will not break the casino ToS.
