I don't think that's necessarily true. Using quantum mechanics as a basis, but really any statistical system will do (thermodynamics, multi-body systems, bacteria populations, etc)... everything is random. It's impossible to build an absolute deterministic system for a single particle (whatever that is). Yet we can also reasonably determine all possible behaviors a particle might take, as well as isolate it under certain conditions to increase chances to induce specific desired behaviors. On a macro scale, we can reliably predict how systems of particles will behave 100% of the time.

So, we may have free will to do whatever we want as individuals, and it not impact and "great plan" in the same way that we don't worry about all the water in a cup suddenly evaporating in an instant.
