Nope. That’s just a shitty article. Here you can read that 1) what they compared was not T-rex’s DNA, it was collagen and 2) the results confirmed the closest relatives to dinosaurs were birds in general, not chicken.
By the way, dinosaur DNA might indeed have already been found (in a hadrosaurid called Hypacrosaurus), but it’s not entirely sure yet.
Chickens are the closest modern ancestor of the Tyranasaurus Rex. Oh how the mighty have fallen.
Is it really chickens specifically that are the closest relative, not any other bird?
Yep

So it’s inclusive of ostriches and not exclusive of chickens, so what I said was entirely correct just incomplete.
Technically yes. You forgot to include all other birds. Chicken and ostriches are mentioned at the beginning of the article as examples of birds.
