Yes, but none of that refutes the argument that we lack free will. The trillions of interactions leading up to an ‘action’ on our part can be random, determined, or some mixture - but they still ‘cause’ our next action, rather than our 'free will ’ causing the action. If you believe in free will, you believe in a magical quality we possess which is somehow neither random (else it wouldnt be ‘will’) nor determined (else it wouldn’t be ‘free’)
