Every tutorial you watch should be able to help you extend your knowledge on methods of completing certain tasks. I suggest you really take some time to focus on a tutorial series with networking and really understand how everything works so you can replicate it with various different projects.
These skills you gain from the tutorials you watch should be sufficient enough to land a junior position at a company. Showing these skills in a portfolio on a website would be the easiest way to allow someone to view your work. You’ll learn a lot more as a junior developer than watching anything on YouTube or probably even in school.
