How they test matters
They aren't giving them to people to fold and unfold thousands of times. They are having it done by robots, which do it exactly the same way every time. In the real world, sometimes you slam it shut and sometimes you carefully close it, sometimes you torque it a bit to one side while pulling it open, it sits in your pocket and gets squeezed (perhaps a lot, given how thick that thing would be when folded)
So no, having a robot fold it 100,000 times would not make me feel confident it will be fine in the real world.
