My answer to that would be down to whether you're judging yourself (imposter syndrome and self worth and competency) or judging the amount you don't know (objective assessment of the field and what's left to learn).
For those not familiar with Dunning-Kruger, it's the cognitive bias where people overestimate their ability when they have little knowledge. But on the flip side, the more knowledge you have, you can end up underestimating your ability. Which, in this case, can look like imposter syndrome.
