This makes no assumptions that the material world is all that exists. There simply are no alternatives - either the universe obeys rules, or it does not.
If you say that the universe is entirely deterministic, then how do you explain quantum fuzziness, that does not follow a rigid set of rules, as does gravitation.
If you say that the universe in entirely probabilistic, how do you explain the ability of gravitational theories to make predictions about planetary motion?

You can't be "partly" deterministic or "partly" probabilistic. Quantum theory seems to imply that the universe is probabilistic, but this is NO contradiction with the ability to predict things on the level of a planet - probabilistic means that some events have certain probabilities of occuring, rather than absolute certainty. Thus, there is a VERY LARGE probability (bordering on 1) of our predictions about planetary motion being correct, just like there is a VERY LARGE probability of 10^100 coin tosses resulting in about 50% heads.
If the rules do not constrain you, but merely provide a guide, than those rules are not deterministic.
The rules aren't a "guide", but neither are the a "constraint". The rules are "obeyed" to the letter (in a deterministic universe), but such "obedience" isn't met with resistence. I have a certain mind, which reacts in certain ways to various stimuli; just because it reacts deterministically doesn't mean that it was "constrained".
