Default Vented brake rotor?

Chevy Impala LS 2012
The original front brake rotors are vented. They are about 30mm thick. I got the part number from ACDelco and ordered it from Amazon. The rotors should fit my vehicle per ACDelco and the description implies that the rotors have vanes. ACDelco Gold Fully Coated Front Disc Brake Rotor | 19340372 | GM Parts
I got it today. They look completely solid to me. The way I drive it probably doesn't matter, but they are 14 mm thick as opposed to the original rotors that are approximately 30 mm thick.
Will my original calipers, assuming there is nothing wrong with them, work with those rotors?
