So Can I Just Start a Self-Priming Pump Any Time, Even If It's Dry Inside?

No. A self-priming centrifugal pump must have water in the casing in order to operate. You cannot pull any self-priming pump right out of the box, turn it on, and expect it to pump. If it's full of air, it won't prime. "Self-priming" refers to the pump's ability to repeatedly turn an air/water mixture into a pumpable fluid -- NOT the ability to create a vacuum (literally) out of thin air. In fact, you should never try to run a self-priming pump without water in the casing. It's dangerous and will often lead to seal failure.
