That was the understanding until the CIA released a bunch of documents in 2017 which revealed that it was such an abysmal failure that they almost called off the entire thing.
The attempted coup brought out a lot of pro Mossadeq protestors. It wasn't until the 19th when clerics organized anti Mossadeq protestors that it took hold.

Idk which is correct, but I really wouldn't take Wikipedia at face value for this kind of topic. Would dig into the sources if I were more interested.
