Not according to traditional terminology.  What you've done is used 
Abstract Data Types, which is one of the most basic forms of abstraction 
that anyone should learn in any programming language.

Of course I've seen quite a few programmers who don't have enough 
discipline to use consistent abstractions unless they're forced to 
encapsulate things in classes.
