This is why high achievers who have had a taste of the vast amount of knowledge out there are likely to suffer from what psychologists call imposter syndrome, the feeling that you are not really up to the job, even though, of all people, they are (Clance and Imes 1978; Brems et al. 1994).
having impostor syndrome is a sign that you aren't an impostor. You aren't experiencing the Dunning Kruger effect.
