It is possible since there are already onlince gambling sites that were made and accepts Bitcoin and Other cryptos to be exchange in chips.
I guess Sooner or later land based casinos would recognize Bitcoin. But as of the moment no land based casino are accepting Bitcoin to be exchange.

In the case of Bitcoin, only selected countries do have accepted Bitcoin as a form of payment.
