I need help understanding the dark-matter aspect of this (www.youtube.com)

I enjoy conjecture and CGI and what-ifs. But the idea of primordial black holes being dark matter? Huge gravitational wells repulsing things? I'm a layman, so this seems as implied by word choice and emphasis.

The question of dark matter is something that is gravitational and invisible spread in patches around the universe that can't seem to be tracked. The idea of primordial black holes (that are clearly gravitational and they are invisible) fits the amount of dark matter predicted by our mathematical calculations under specific circumstances which are detailed in the video. It's a theory, it's not proven, but would answer a lot of questions.

As far as the gravitational well question... there's only so much matter that can fit into an atom sized aperature, and all the rest of the matter trying to fit in ends up rotating around the black hole so fast that it flings away other matter trying to get in. Does that help?

It's a hypothesis. Theory has a very different meaning
