Jokes aside, "exact" can refer to either accuracy or precision.  I
suspect that the difference between the two is what's causing trouble
here.  (What is the difference?  Accuracy is how close a number is to
reality; precision is how small a number's error estimate is.  For
example, I could say that there are 3,418,029,600 plus-or-minus 10
humans on our planet at the moment.  This is a very _precise_ number,
the error estimate being about three parts per billion, but it is a
wildly _inaccurate_ number, being about half the actual figure.)

I suspect their "approximately" really meant "this is the exact number
we have in hand, but we're not all that confident that it truly
reflects the reality".
