Your mental model isn't necessarily wrong. The phrase "salted hash" generally refers to something more plain than PBKDF2. PBKDF2 is technically a "Key Derivation Function", but it can also be used as a "Password Hash Function". Password Hashes generally use a hash function and a salt, yes, but they also incorporate other important factors as well, commonly a work factor and some "hard" computational problem, so it's unfair to call them merely a salted hash. PBKDF2, along with password hashes in general, do indeed do everything a "salted hash" would do, but importantly, they also do more.
