It's not exclusively an ADHD, neurotypical, OR neurodivergence trait. Severity and effects on life matter. It can be a trait associated with a myriad of executive dysfunction disorders (e.g. Autistic Inertia), ADHD, anxiety, and some personality disorders as well.

Severity and effects on life, that's the first measure to look at before asking "But everyone is like X or Y, sometimes".
