I am not a biologist. One way or the other the body is in a constant state of flux. Even if 90% of body is regenerated over a period of time, it is still a great wonder.
But while it applies to many cells over varied lengths of time (up to many years), it doesn't apply to all cells.

So the idea does apply but not exactly as you claim and it's definitely not absolute, even for atoms, let alone cells.
