GPS is actually far more accurate than that. There is deterministic jitter introduced to make civilian use cases precise to only a few meters, but military equipment has the algorithm to subtract that jitter and achieve precision measured in centimeters.
Anyway, that statement is highly misleading. They were comparing to previous inertial navigation systems, not GPS navigation.
Didn't they turn all that jitter off like 15 years ago?
Edit: I ran a little experiment and zig-zagged up a bit of hill on the bike this morning and the GPS/Galileo/Glonass unit resolved it easily. However, it didn't quite agree where the road was.
The road, was pretty narrow.
