At this point, "Absolute Shazam" is Teth-Adam, not Billy Batson, right?
In ABS #18–21, he's consistently referred to as "King Shazam" or "Teth-Adam," and no one calls him "Black Adam."
To be more precise, Absolute Shazam is technically both, although about 99% of the character is based on Black Adam. He seems to combine Black Adam's story with Billy's defining trait: being a boy who transforms into a superhero.
Don't get me wrong—I'm not complaining at all. I actually think that choice makes a lot of sense. The contrast and similarities between Absolute Teth-Adam and Absolute Kal-El are portrayed really well.
The parallels between their origins, powers, and appearances make King Shazam feel like a natural rival to Superman.
Really good read!
