@Abdulmunim, you have watched all 7 courses in the playlist Becky shared above?
To learn and retain the knowledge in any course/tutorial, wherever it is on the internet, you need to practice what you are being taught.
After each lesson you watch, open up Blender and replicate what you see in the lesson.
Don’t stop there though, take it further, play around with the settings, colors, nodes, etc., etc., that are covered in the lesson.
Watching and copying isn’t enough. Try creating something of your own. It doesn’t matter if it turns out terrible.
Without trying, we never succeed.
Other courses to follow the fundamentals include Press Start and Pothead.
These are great projects to help develop further knowledge of the fundamentals (minus animation).
Four key words when learning any new skill…
Practice, practice, practice, repeat.
