There's provably a major shift would gonna happen and the only affected on this is those local casinos.
But for online crypto gambling sites? I guess not because people would provably seek for alternatives and discover that they could able to continue those things that they want and use crypto to deposit on the online casinos they want to play.
I read that most of those digital wallet platform adopts crypto and they can buy any coins they like using their native fiat, so with those for sure that there's no big effect would gonna happen since gamblers can continue their usual activities.
Companies with online platforms and services are more flexible than traditional companies with physical officies for operations. Blockchain, cryptocurrencies and web3 wallets allow online casinos to easily move around domains, get licences in countries that accept gambling while they can avoid legal issues in other countries.
More and more casinos have Web3 wallet deployments in order to give their customers diversifying options so that they can become more attractive with potential users than other online gambling competitors.
