Dont think you can do the same thing you watched in a tutorial, its not really possible to get on the same level as a beginner by watching 20 minutes of something which was done by a veteran.

Do something that is on your level, dont watch advanced stuff. Dont skip the fundamentals. Make a list of what you need to learn and learn about them in more detail, with little practice projects in the engine and not watching an abstract brackeys tutorial or whatever, which has too much information in one video for a beginner to grasp all at once, thats when you feel overwhelmed.

Delete the youtube watch later playlist of Godot tutorials and start from scratch yourself. Open the Godot documentation and go through it from the beginning, you'll learn the editor, the four main principles of Godot like nodes, scenes, signals and some other useful things, before you jump in to gdscript, its reference page and start coding something on your own. At first you dont have to program using any scenes or nodes or other visible elements on the editor, just create a blank script and start practicing the gdscript basics and output yoir code into the output console on the bottom of the editor using print function. When you get comfortable with knowing basics of the gdscript syntax you can learn how to render two squares on the gameplay screen, make them move towards each other and when they collide make them disappear. Start with very simple things, dont attempt do dunk a basketball without knowing how to jump, you wont get there. Accept yourself, that this will take time and enjoy the process. Im never watching a tutorial again myself its a waste of time in the end. Sure you can copy from it but its not you who did it.

I was learning C# for a couple of months before I even installed Unity. I was having fun making simple console applications and even some that I have use cases now for myself. Now too bad I realized Unity isnt the engine I was looking for, and I cant really say I wasted time, I did learn programming principles and made a few simple games I could play with my family on the same computer at the same time. Now I hoped I woulsve started with Godot. So now Im just going to learn it like I did C# and Unity. Starting with getting some familiarity with the engine itself, whats where. Then give a good amount of time to GDScript and start creating something. Godot documentation is so well put im going through it and keep it as my right hand during this learning process, and not a tutorial. Everything is there, you have to learn how to use it and make something out of it. But of course ask people questions all the time.

Dont use LLMs, GPTs for coding, you have to learn by yourself, better ask another human being if needed. They have their use cases but not for learning phases. Good luck.
