Does types being terms imply your dependend theory is considered polymorphic?

Question

In the introduction of the book by B.Jacobs, "Categorical Logic and Type Theory" (it's online here), he classifies type systems into three general flavours: Simply typed ones, depended typed (term depended types) and polymorphic types (type depended types). He says also there are also mix types.

Now if you start out with a dependently types theory and introduce transitive universes, hence forcing types on the level of terms, are you automatically speaking of a polymorphic type system then?
