Why do things flood into a vacuum?

So I’m aware it’s because of pressure difference, but why does that matter? Why does the pressure try to equal out immediately and not just slowly wait as things move into it like they would in ambient pressure?

Remember what pressure actually *is*. It’s the physical effect of the atoms of the gas pushing against each other and the boundaries of their container or against the boundaries of an area of different pressure.

The reason why things would move slowly when pushing against something with ambient pressure is because of that ambient pressure, it’s pushing back. A vacuum has no pressure so there is nothing to push back or stop something else flooding in.
