Does that mean no one who lived in a Vault at all?

Not associated with the game or the GM, but I love Fallout more than most things in life and figured I'd drop in to let you know, "The Vault Dweller" is the official title/nickname/epithet of the protagonist for the original Fallout, just as their descendant is "The Chosen One," Fallout 3's character is "The Lone Wanderer," New Vegas is "The Courier," and Fallout 4's is "The Sole Survivor" (despite that title being a total bold face lie >.>). So what the GM is saying in that statement is that your characters are not "walking death one man army gameplay protagonist" types, not that you can't have come from a vault.
