The point of money laundering is to conceal the path of funds. Changing your money into chips and then your chips into money (at different times) accomplishes this. Casinos are remarkably light on the documentation side compared to financial institutions. When you change money into chips you don't get a receipt or have to sign anything, you just get chips. Similarly, you don't need to do anything special to switch chips back into cash. If you're trying to make the funds look really legitimate you can even pay tax on your gambling "winnings".
