A casino is a profitable business so it needs a license to be considered legitimate by the government and a casino cannot be anonymous if it has a license, but this is pretty much the same way CEX works.
So the casino will keep a close eye on its users if caught then they will take action against the user.
The government cannot be blamed even if they themselves are laundering the money, and usually the government is unlikely to do so.
Y you're right, casinos that are already legal and licensed by the local government will have the authority to enforce KYC at a certain withdrawal rate, so this can prevent money laundering from happening because they will know who is trying to launder money.
Some actions will certainly be taken if a player tries to commit money laundering by freezing their account and issuing a warning that they have committed a violation.
And the discussion about the government that may carry out this laundering will be related to individuals or individuals in the government,
because of the government, it consists of many parts that jointly regulate the government.
Those who individually violate and commit money laundering can also be investigated and will be arrested if guilty.
