I learned to play hockey about 5 years ago. Part of that was going to stick and puck sessions during the week, where I could basically do whatever I wanted; work on skating, stick handling, etc. Sometimes there would be literally no one else at the rink, and during those times it was super fun being a noob. I had a ton of stuff I could work on, and I would see progress from week-to-week. I started playing on a real team not long after starting to learn, and the games were the opposite. I just felt super embarrassed the whole time.
I have thought about this phenomenon with regard to the internet a lot. Online it's easy to be exposed to videos and other content produced by people who are literally among the best in the world at anything. This means we start to measure ourselves against the most unforgiving yardstick imaginable, which makes being a noob (or even "normal") even more painful.
No matter what you do, for anything you put effort into, you are probably above average at it, when you include not just everyone who tries it but also everyone who hasn't even tried.
You can be the worst person at your job and still do a job worth getting paid for.
