Because the race isn't extinct?. Besides, with that logic it means that there would be more vampires and were wolves so on. Just because Tolkien said that a species went extinct doesn't mean all the other ones aren't.

As well it was said before that it is probably all from document from the northern parts of Middle Earth, not from just him, so the scholars won't be able to down to Umbar and check how many numeoreans were still alive.
