It’s pretty misleading label for the estimate. It’s the age you get when you reverse extrapolate current physics to the point where current bodies converge in space and time.

It’s possible space and time continue beyond that extrapolation point. No one knows.

If there is no way to know what is earlier than that point, then it meets the definition of the starting point for the observable universe.
