So as we know for a person to get electrocuted a circuit needs to be completed. You cannot stand on a wooden chair and get electrocuted. So when you stand on a wooden chair and touch a live wire, how does the electricity figure out that you’re standing on an insulator? Does the electricity pass through you first before failing to complete the circuit because of the wood?

Yes. The electrons basically push into your body in a tiny fraction of a second, then once your body has a few too many electrons, they repel the other ones trying to come in. If there was a complete circuit, they would keep going in one part of your body and out through another part.
That’s for DC of course. AC is just DC that changes, so the same thing applies, but it reverses 100/120 times a second. It’s still pretty tiny even when it’s happening 120 times per second.
