Huuuuuge difference. Stepper motors have a very specific construction involving two or more independent stationary magnetic coils with "teeth" and an unmagnetized rotor with matching teeth. Energizing the coil in a specific order makes the teeth in the rotor line up with the teeth of the coils in a specific order. So you energize the coils in a pattern and the rotor makes tiny little steps of rotation.
A continuous rotation servo is a more standard brushed or brushless motor with integrated feedback device and control logic.
