I’ve worked with three incredible developers who I’d consider 10x: people who can reliably build a solution quickly, or debug problems that go deep into the OS. One would fit your description, one is a mom who shuttles her kid to after school stuff, and the other is a really nice music nerd.

Like the post states, some people are in the right place at the right time: they have the right background and temperament to do really well at their job. They don’t need to be shitty people.
