The best "tells" come from bets, raises, calls and checks. Not how the chips are handled, but the actual action. Put the hand together so far and prosper.
As for twitchy hands, gum chewing, chip fondling, pupil watching and the rest - - - mostly it is garbage for the typical player. No doubt the best "readers" can do magic. The rest of us need a lot of observation to figure out what secrets people divulge by mistake.
And just when you think you know a long term villain, something strange will happen in their lives to throw everything off.

I’m pretty good at reading hands but it mostly comes from bet line hand progression and human tendencies.
I give off fake tells all the time to induce call or fold.
if you see a tell and it’s kinda obvious, I wouldn’t take it to mean much
