The answer depends on the person honestly. Object and Mesh data can be a very confusing topic in particular though. I wouldn’t be overly hard on yourself.
I just started tutorials and then played a bit, then went back to tutorials and then tried playing and then went back. I only remember 10% most of the time if I am being brutally honest. But the more I play and try to teach the more I end up having desire to answer my questions.
Also, don’t be afraid to ask questions as they come up. The answers may not always come quickly but I doubt you are the first person to ask them and you are definitely not the only one who doesn’t understand.
Ask often after trying to understand things and post pictures that reflect the struggle with arrows pointing if possible. I use greenshot for screen capture (free program like blender) pictures and I make arrows all over things I don’t understand or want to highlight.
