Not necessarily. We're talking about if the white man had never come to America. That means there wouldn't be advanced medical care, big agriculture, highways, cars, roads, planes, horses etc... I don't think the native population would have gotten that large. Like all mammals nature would have thinned them down every once in awhile. After all in thousands of years they didn't overpopulate their range and we're talking less than 600 years in this scenario.

All we can do now is speculate what could have been, but we don't know it for sure.

True. Just speculation
