Actually that idea is intuitively easy to understand once you consider how large Siberia is. It's hard to imagine humans could extinguish any species there, even one that's so hard to miss.

But if course, we don't really know how Mammoths lived, how far they travelled, where and when they bred, etc.

Maybe all humans had to do was wait on some river crossings in a specific time of the year because some instincts told the Mammoths to traverse that route every year before mating season. Or maybe we didn't extinguish Mammoths and they died from some contagion (why should that only happen to humans?).
