I'm just meaning sort of statistically - if we somehow knew only another 100B people will be born, then either we continue along our current growth and burn through 100B in a thousand years or so, or the species lasts for millenia but the total number of those people is only 100B, so the population never got huge again. This is really just kind of an abuse of statistical thinking - you're not wrong at all that populations recover, but in our case if that happened we're back to saying that we were born in the first 5% of humanity, which I'm saying is likely not the case.
