Ofc that's only at this point in time. Things might change really, especially if you consider how dApps can be the alternative for players in countries where gambling is banned/illegal.
The world is heading into automation and full digitalization of everything. AI, Blockchain, and Quantum Computing will become part of our lives in the future. This means we will rely less on middlemen, and more on decentralized protocols/technologies. We could have some sort of "hybrid" casino where there's no central operator involved, but the dApp itself complies with KYC/AML and accumulates profits for its creator (the developer of the contract). There will be a radical transformation of the gambling industry as we know it. Perhaps, it will take decades before we'll be able to witness such a thing. At least, the idea is there. Making it a reality is another story.
I'd expect decentralized gambling dApps to improve to a point where it becomes cost-effective to gamble on them (low fees) without delays (near-instant transactions). For now, centralized gambling will continue to dominate the industry.
I agree that there will be automation, it's a fact. However, a hybrid casino is an idea that I have been talking about here. Centralized companies will need to adapt to this, as will decentralized companies, both focused on capturing and facilitating customers.
