I can't speak for everyone, I've definitely seen people make the transition or at least bring in-person tournaments into the games they play. I suspect a lot do just prefer online because of how convenient it is and don't really explore in-person events.

For me, there was definitely a high level of anxiety and nerves when I sat down at a table for the first time again after playing online for a while. But it gets easier and easier to shake that off and just get into the flow of watching betting patterns (which is the main thing you have to work with online) which to me was always the primary source of tells rather than anything physical. So maybe in my case the answer to your question is yes haha :) though it didn't seem to impact me negatively much.
