No, I certainly don't believe the Tsaesci to have literally eaten the humans of Akavir; otherwise, there would've been no "Blades" organization forming to aid the Dragonborn Emperors in the first place.

And then there's, "Duadeen", who MK (writer of the Redguard comic book) confirmed back then to be half-Akaviri.

I'd say that this pretty much confirms that the Akaviri humans are still around.
