angular momentum – If dark matter only interacts with gravity, why doesn’t it all clump together in a single point?

The Question : 81 people think this question is useful I’m a complete layperson. As I understand, dark matter theoretically only interacts with the gravitational force, and doesn’t interact with the other three fundamental forces: weak nuclear force, strong nuclear force, and electromagnetism. Those are my understandings going in. If I’m wrong, please correct me.
