Trying to work out the definitive, exact ages of long running comic book characters is often an exercise in futility, even without all the multiverse crises, flashpoints and what have you. Young characters can age up and actually close the gap with older already established characters and many other characters don't really age at all. It's nuts.
Of course the advantage of an adaptation is the freedom to actually have third act type consequences and growth.
Personally, I'm liking the big brother/little sister dynamic they're setting up between Richard & Rachel. While not materially similar, both of their It backstories resonate with each other just enough to make it credible that Grayson would become so personally invested. Also in the process perhaps gaining some insight and perspective into his own relationship with Bruce as he starts to step into a similar one, but from the opposite perspective.
In the comics, Teen Titans seemed unusual for a DC title as the team was (in various incarnations) portrayed as a surrogate family dynamic, which was usually more of a Marvel thing. So I'm glad they seem to be sticking with that core idea. (Sure, the Bat family is the Bat family, but's a somewhat different animal.)
