QM and chaos theory are both fully deterministic, even though future prediction is impossible in practice in some cases. We only call them non-deterministic because we can't ever hope to determine outcomes ahead of time in practice- NOT to say that the outcome isn't ultimately from a natural flow of causality. In fact, ultimate causal determination is proven for both. Consider Broglie–Bohm. There is no true randomness. Not in math and certainly not in QM.
