hi,

normal DC gear motor is different from servo.
servo can be used in positioning, but DC gear motor, we hardly knows the position.

Servo is actually referring to a system with feedback or error-correction signals to help achieve the desired output, such as position, speed, temperature and water level. Without servo, a system is open-loop.

So a servo motor is a motor with feedback signal to control the position of the shaft or speed of rotation. I think you're asking about the rc servo motor. This site gives you the comparison:
