The reason it does not trip is because of how the tester is designed. The only way it can simulate a ground fault to divert some current to the ground wire. The GFGI would still work. However, an open ground should still be fixed unless it is a converted two prong socket that is properly labeled with "No equipment ground".
GFCIs don't rely on ground for circuit protection. They trip because of an imbalance of current between the hot and natural. Even though receptacle 3 does not provide an equipment ground, it will still provide protection.
Yes. But you'd still want to fix that open ground, so that if any 3-prong appliance plugged into it had an internal hot-to-ground-fault, it would immediately trip the GFCI, or the panel breaker. Without ground, the metal casing of the appliance would possibly remain hot until someone touched it. The GFCI would (hopefully) shut off the moment someone touched it, but that's still a higher-risk scenario.
Yes, but it still is a problem and a code violation unless it has been used to replace a two prong outlets on an old house and it is properly marked. Getting singed even with a GFCI hurts and it might kill someone with a heart condition.

Is there a video showing the fix? I've got a room full of "open ground" , yet they all have a ground wire attached.
What if they are all testing open ground?
So there's a open ground and you know it's wired correctly then you check receptical number 3 and it's wired correctly. Where's the problem?
What are the setting on that Klein tool?
I get one lite on right only
Open ground I do believe
