> If I flip a coin in a deterministic universe, it's still "random" (air flow, force exerted, etc), but if I "rewind time" and play it back, I'd get the same result.
Couldn't quantum mechanics mean this is not true?

I view "rewind and play back" essentially as replaying the exact way the quantum states collapsed. Although quantum mechanics are probabilistic (whether you believe in multiverses, Copenhaguen, etc.), the key here is that you're replaying the same probabilistic results and not "throwing the dies" again.
Or maybe I misunderstood your point?
I'd also argue that this is Mario Party using a PRNG. QM do not apply!
But since time travel is impossible then maybe it makes no sense in general to talk about.
Plus as pointed out the OP does say it was a deterministic universe (but I would have thought that is not what we are in due to QM)
