You can’t do this by touching the battery terminals because your dry skin won’t transmit the electicity. You’re just touching battery terminals.
If you hold a AA battery in between your finger and thumb, you’re also not short circuiting it. You’re just holding it by its terminals.
But if you hold an unfolded paperclip to both sides, you are shorting it.
As far as I know, there is not a large population using “short circuit” the way you were (just touching a battery terminals).

No, there is absolutely current flowing when you touch both terminals, it’s just an incredibly tiny amount. You can do the math yourself and see, it’s a basic application of Ohms law. The formula is (I=V/R).

Shorts are unintended low impedance paths.
Sure, there is technically current flowing, but it is small enough to be considered an open circuit for engineering purposes. There is leakage current for every insulator, we don’t call it a short.
