This is not accurate, they use clocks that run ever so slightly slower

Don't know the exact number but roughly the scale. We are talking about a millionths of time going faster, so over 25 years.. maybe a couple seconds or so younger than we give it credit for.

The satellites do get their internal clocks updated by the control segment fairly regularly, but you're right that the reason isn't the accumulation of the relativistic error.
