It detects an imbalance between the Hot and Neutral There is only 3 paths in your household system. Hot, Neutral and Ground. If current isnt flowing back on the N, then it MUST be going back through ground.
GFI's only trip on current leaking, or passing to Ground. Not the GI's ground plug, but ground anywhere. Ground is Ground, common point electrically throughout the house and, yup, you guessed it, the ground outside too

I know what I posted & I know ground is ground, a common reference. The point I'm trying to make is, the GFI will work to protect you from getting shocked without the GFI itself needing the ground prong built into it.
