The learning is a process. You are human. Humans do not stick with a single task. You will start with the basics. Doesn't matter the source. Then will write scripts. You will search for a better way to do something. This involves a lot of googling and "eventually" you will run across those third party libraries. You will play with them. Then you will start to write real programs which actually do something useful. Here is the break point. In this moment you will learn only what you need to know to accomplish your goals/projects.
Exactly what happened to me. Doesn't matter if you use the third party libraries or only the standard ones. It is possible to reinvent the wheel as you strain to accomplish something but you will learn a lot wasting your time. So is not a waste as long as you practice and learn from those with more experience and your own errors. Just do it.
Start from here for instance. Really, doesn't matter where is your starting point. It's a journey
