There is this contradiction in my head regarding free will. I can't solve it.

Against free will: I assume the universe is probabilistically deterministic, meaning it is a combination of deterministic functions and random variables. For given realizations of randomness, it is purely deterministic. Therefore no real free will exists. The universe, including our thoughts and actions, is just the result of functions and randomness realizations that we can't choose.

But: Consciousness is real. At least I have it, that's what I know for sure. I'm aware that lazing about is nice but not good for my grades. I have the choice between lazing about or learning and I have awareness of many aspects of both options and that I have to choose one.

I'm having trouble to accept that it is not free will when I actually choose one of these two options. Can consciousness be real and free will not? Doesn't free will follow from consciousness?

Where are my thoughts wrong?
