When you make a difference in potential, it creates an electric field within the metal, electrons in the conductor tend to drift to the more positive side through the path that offers less resistance, thus creating an electrical current.
It’s all about the fields, all the real work happens outside the wire, the electrons are just going for a ride. (not to imply it would work without them)
No, it’s weirder than that.
