Well... it's complicated. We need to be careful about how we define and use the word "determinism" in this context.

The universe is deterministic within a rigidly defined spread of probabilistic "allowed" outcomes.

This is pretty much what QM has revealed to us.

For the systems which we can model perfectly, we see exactly this kind of causality. There are certain "allowed" evolutions of the prepared system, and those outcomes will happen at very well-defined probabilities. Plenty of systems will have only 1 allowed future, which happens at 100%, but plenty systems are not so straight-forward.
