Gambling is a satanic act that opens the door to other crimes.
Not all gamblers does have that time of mindset. There are charities that are dedicated from the profit of casino's so helping the charity is an act of what?
Yes some casinos do donate the funds to charity but i haven't seen any charity claiming they receive donations from such casinos either way even if the money is donated i have never seen it utilised properly
The government is also responsible for putting the tax that comes from the casino to send directly to these charities. Why do the charity have to claim that they receive donations? You don't know that there are donations that coming from them that wants to remain hidden, helping without any exposure.
