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.
