headfirst design pattern, does abstract factory pattern inherently employs factory pattern?

I've read through this article. What are the differences between Abstract Factory and Factory design patterns?

but I still have some uncertainty regarding the Abstract Factory Pattern. My question is whether the Abstract Factory Pattern inherently employs the Factory Design Pattern as a part of its implementation. I'd like to understand if the Abstract Factory Pattern typically incorporates the Factory Pattern for creating its related objects, and if so, how these two patterns are interconnected in practice.
