Correct.
If you’ll notice, Blackbeard actually has a ton of “fake” titles.
He was a Yonko Commander, but never actually loyal to Whitebeard and betrayed him when the time came.
He became a Shichibukai, but only to advance his goals and never intending on honoring the title.
He is called an “Admiral”, but he’s not a legit Admiral and more just a typical pirate fleet captain.
He’s a Yonko, but the title of Yonko is something he has no interest in or ever wanted.
Teach has had a ton of completely fake titles, his only real interest is being the King of the World.
Being a Pirate for Teach is just an extension. Teach doesn’t actually care about piracy or being a pirate, this is just a stepping stone for him to amass power.
So yes, Teach’s true calling is not as a pirate but as the King of the World. Davy Jones was probably the same, not a pirate at all but the King of the World.
