Yes, a 30 ranger soloing Orcus is similar to a 1st level character being able to solo the black dragon at the end of D&DXP's Scalegloom Hall - a 4th level solo monster. That one was able to usually kill or at least knock unconscious at least 1, usually 2 or 3 out of 5 1st level PCs (barring horrible rolling on the DM's part).
