Yes, but deterministic is not the same as predictable.

That doesn't necessarily follow. Approximations can be made but in general
an exact solution to the 3 body problem would require an infinite (and not
just astronomical) number of numerical calculations.

How long the prediction remains good depends on how strong the
gravitational field is and how rapidly it changes with distance; the
greater the strength and rate of change the worse prediction.
