Yes, but you can never tell how good someone really is unless maybe they make a video just playing thru a real amp, no backing track, no gate, no production or anything. Just in a room thru a real amp with a mic or even a cell phone recording, so you can hear every little thing. Then you can tell if someone can really play!
When you start out with no bad habits, you can get that good. Unlearning the bad habits slows down the progress.
