> They set up entangled particles in a specific way where they turn out to behave exactly the way that "wormhole math" predicts that they should.

This is the correct reading of this result. ADS-CFT correspondence says loosely that the maths of some gravity things matches the maths of some quantum things, when you look at them in the right way. In this experiment they set up the quantum things, looked at them in the right way, and (through the lense of the maths you have to do to look at them the right way) they behaved like the gravity thing. The specific gravity thing they behaved like is a wormhole.
