Soap acts in two ways. First it physically removes dirt, oils, and dead skin which has germs by making them more amenable to being washed away by water. The physical action of rubbing also helps. Second if it has an antibacterial then that is an added effect.

Hand sanitizers are primarily alcohol based. Alcohols denature bacterial proteins.
