There is a level of uncertainty and probability and the smallest level of our universe. The deterministic model of the universe has been put to rest a century ago.

This is true, what we instead have is a probabilistic model of the universe, which still obeys very clear statistical rules and probabilities, also seemingly leaving no room for free will.

A dice roll doesn't have more free will just because it's random.

No. On average things are average. So while not everything can be fully predicted you don't usually need to. A laser, a transistor, a diode are all devices that depend on QM theories being true. We have lasers, we have screens, we have neat flashlights, we have computers. Just because we can't say everything doesn't mean we can say nothing. Every time your lungs fill it is only because vacuums are unlikely, not impossible just unlikely.

Uncertainty doesn't save free will, at most it sets limits to it.

• if you agree to this hypothesis, turn to page 72 70% of the times
• if you disagree, turn to page 72 40% of the times
• if you're viewing this through polarized glasses, turn to page 72 80% of the times
• if you're an electron, rotate 360° to page 72

I think you are not getting it quite right. Those "low level" things are predetermined. Where you get the uncertainty is that there is always a bigger or smaller picture.

Determinism and uncertainty are both perfectly compatible with each other.

Unless superdeterminism is true. But does it make a difference anyway? "Free will" is overrated.

The fact that quantum mechanics models physical processes stochastically does not mean that there is free will neither that the universe is non-deterministic. This statement is strictly true.
