not sure what the difference between a simple subject, simple predicate, complete subject and a complete predicate are
The simple subject is a noun or pronoun. The simple predicate is the verb.

Katy is the simple subject.
is working is the simple predicate.
The complete subject is the simple subject and its modifiers. The complete predicate is the verb plus other words that go with it.
