No, definitely NOT! 
For a PWM you have two defining values: the frequency (or equivalent the period) and the resolution. The frequency value tells you how often per second the full duty-cycle is run through, the resolution tells you the granularity in which you can set your duty cycle. A resolution of 10 means, that you can set the duty-cycle in steps of 10%s. For servo control you need a very high resolution but do not need a very high frequ, for motor control its often the opposite...
