I do agree with this statement on the meaning of f-number, but it is confusing since it is the format + f-number which determines the amount of light captured by a picture, which accounts for the final Signal-to-noise ratio of a picture

Well, the actual amount of light is determined by the T-stop, not the f/stop. If you have a complicated lens, quite a bit of the light might not make it all of the way through the lens.
