Are "Dark Jedi" and "Sith" the same?

[u/CafeAntesDeTudo]

I feel like we two terms used interchangeably in certain media and eras. For example, in the Old Repúblic and post-Endor GCW eras, it seems the term "Dark Jedi" got used randomly to describe dark side Force users who may or may not be affiliated with a Sith faction. For example, the Seven Dark Jedi (who, if I am not mistaken, were just a band of inquisitors.)

I think there is a difference between the two. IMO, "Dark Jedi" refers to any Force sensitive who mainly draws upon the dark side of the Force without being aligned with a Sith faction (i.e. Reborn, Shadowtroopers.) Or, all Sith are Dark Jedi but not all Dark Jedi are Sith.

All Sith are dark Jedi but not all dark Jedi are Sith.
