Your simplification although partially true is not completely accurate. Yes the electric potential as a voltage activates the FETs use in this CMOS technology which causes the transistors in the circuits in a processor to switch allowing for logic circuits. This is a simplification though since you fail to compensate for the actual currents that exist within the channel of these FETs which do allow both electrons and holes to move through a given circuit. Like someone else stated here the charge carriers undergo actual displacements (which are caused by the electric field at an input) in accordance to their mobility, but all of this is a probability of any charge carrier moving some distance. On average the carriers don't move very far.
