If I can continue the nitpickery, plenty of computer algorithms are deterministic but also pseudorandom--including Markov chains. Only when the randomness is outside your control are things truly non-deterministic. A simulation with many possible outcomes is still deterministic if you get to choose the "seed". In other words, statistical permutations are deterministic if you control all the input variables (in terms of computer science; physics is another story).
