I don't think this is too difficult for the average person to understand.
Actually, many things can suck and do all the time. When you lower the pressure on one side of an object or place, the "normal" pressure on the other side of the object or place, combined with the lower pressure opposite causes a force that moves the object, or moves the air within the area of divergent pressures.
You're absolutely right that it's basic, but it appears you're simply not happy with the way the museum phrased it.
Modelers talk all the time about our motors sucking air into the carbs. It's the same thing. The model motors aren't pulling the air in, they're creating internal pressures that are lower than the atmospheric pressure outside, and the atmosphere pressures air into those engines. People often make up terms like "suck" that mean more than one words worth of definition.
BTW, I used the word "motor". Same deal.
