This is partially correct and partially incorrect.
They are both in the CBP.
The main difference isn't where they work, it's the laws they enforce. A CBP officer in the airport utilizes exclusions to keep people out, whereas a BP agent is dealing with someone who has already made an entry (albeit an illegal one) and must therefore use deportation statutes or some form of voluntary return (VR).
