That’s not correct. The frequency provides an indication of how much power is being drawn. If the frequency is low then generators supply more power to bring it back to 60 Hz.
If there was not a well known fixed frequency it would be impossible to evenly distribute load over power stations. All generators have a %load vs frequency delta curve built into them which is precisely calibrated.
