It's all about context. When you start out and don't know much, you're going to look at everyone and see them as better than you, even the less than average folks. It's just a function of time and exposure to the work. You will improve over time as you learn and you'll have less and less people that seem better than you and more and more that are "imposters", compared to you.

I work in a field (engineering) where a crap load of people have advanced degrees. When I was younger, I would look around me and feel like I was so behind that I was never going to be able to compete. Everyone was speaking to each other using terms that I had no concept of. It was easy to see them all as up on these pedestals and I would never get there.

Eventually, I realized that the lingo they were using was specific to the work, not to the discipline of engineering. That's just a function of being exposed to the work. As I came up to speed on that lingo, the pedestals came crashing down for the majority of the people I work with because I could see that while they knew the work, they didn't seem to have any special abilities that I lacked and, in fact, plenty of them were mediocre. Sure, there's some that are stand outs, but there's also some that just suck. The average is just a plain engineer...and they're not so intimidating.
