1000 steps Servo motor

TheSuperSewcio @ instructables.com shows us how to control a servo motor in high precision using Arduino:

In many project like CNC machines people use stepper motors. They are probably always more expensive than servos. They can rotate 360°, 1 step = 1,8° (mostly). Servos can rotate only from 0° to 180°, 1 step = 1°. But why are they working this way, inside them we will find potentiometer which rotates as servo (up to 180°), but have 1024 steps.
