Instead, it's typically because either the credit card issuer or the sportsbook prohibits the use. Many credit card issuers simply don't consider gambling an acceptable purchase they may see it as too risky.
The short answer is "no". You can use your credit card to get a cash advance and then use the money to buy chips (or anything else of course) but you are probably already aware of how expensive this type of transaction is. Slot machines accept cash and "TITO" tickets.
Gambling and gaming are two different things. Gaming is when you participate in legal, state sanctioned wagering. Gambling is when you place bets or wager at locations or online platforms that are not permitted in the State, which remains a criminal activity.
