I don’t see how that’s relevant. Plus your last sentence sounds like you’re just repeating something you heard but forgot a part of it, because it makes no sense as it is.
The part they’re misremembering is that if you used 39 digits of pi as pi (not 45), it would be enough to calculate the circumference of the observable universe with a forward error of less than the width of a hydrogen atom (not the distance between 3)
