No, it doesn’t. Every measurement has error. The question is how big. It was minor already back then, but it could be further reduced and with the switch to dematerialised standards that are only possible with modern technology it is reduced even further, but it does have still an error, of course.

By your logic, that’s saying they still get it wrong but it is understandable because everyone will get everything forever wrong. I just find it mildly amusing is all.
