Try this to see for yourself
You are talking to someone that is holding a "secret" answer from you. You tell them, I want to guess, and then you ask yourself the question with them listening. You tell them, is it [ insert guess here ]? And if they exhale and you exhale without feeling uncomfortable you may have a tell. And here feeling uncomfortable may tell you have a different place to put that air but you are definitely reeling, out of the head, from the same place and physical experience.
This is called bated breath. Like when someone is in bated breath, they are excited to tell you something you "didn't" already know. An example of this is feeling like you just gained a teacher's approval in class after answering correctly. Sometimes it's simpler. In poker, you would be guessing their hand at them and they would be exhaling with you, they've been telling themselves their hand.
