[MCU] What exactly is the difference between Thor's "realms" and Doctor Strange's "dimensions"?

I think the 9 realms are all actually physical locations/planets in our dimension, just really far away.

The dimensions in Dr. Strange are not located in our concept of "space," meaning you couldn't reach them even if you had a spaceship that could travel between galaxies in an instant. They are *beyond* space as we perceive it - and you need some sort of specific power to interact with them.
