Mostly, yes, but I do think there's a real point here as well.

As I understand it, physicists don't really know whether the physical world has a finite number of states, or an infinite number. I think they tend to lean toward finite, though.
Even if it's infinite, I doubt it's of consequence. That is to say, I doubt that sentience depends on the physical possibility of an infinite number of states. (Of course, if it turns out the physical world only has a finite number of states, that demonstrates that sentience is compatible with the finite-states constraint.)

Systems can be modelled as finite state machines. Sentient entities like people are extremely sophisticated systems, but that's just a matter of degree, not of category.

Right, because you're in a different state. You'll never be in the same state twice. We don't need to resort to non-determinism.
