Coding tutorials don't teach you how to code. To get better at coding you need to solve problems, and watching tutorials is nothing more than watching someone else solve problems for you.
If you are interested in learning to code, or becoming a software developer, you need to make sure that you're utilizing tutorials in the correct way.
My advice for following tutorials are:
Have a single concept in mind that you want to learn and implement into your own project
Use a variety of instructors
Make sure your coding on your own too
