If your 3-light tester indicated the non-gfci outlet is grounded, and you push the gfci test button on the 3-light but nothing trips it's not protected.

Yes ... a GFCI detects a difference between the hot and neutral wires. If there is fault and current starts flowing from the hot wire, it should detect the hot-neutral current difference and trip.
