It's more of a mouthfeel thing than a thickener. Gelatin, in the amounts found in a good stock, will still be quite liquid when the stock is at serving temperature, but will sort of coat your mouth with flavor even when the broth hasn't been thickened with a roux or cornstarch.

They were pointing out that with meat stocks it depends what went into the pot - a good home made (or restaurant) one typically already has enough to make it “gel” in the fridge. The box types you mostly get in a store didn’t have this, so might want to add if your recipe assumes it.

Ah, got it - your comment(s) make more sense now for sure.
