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?

Imagine a little ball floating through space. Theres nothing else around, so it will keep floating in the direction it’s moving. That’s no pressure/vacuum.
Now let’s say we have a bunch of balls moving in random directions. Occasionally they’ll bump into each other, and they’ll both change direction. That’s pressure/an atmosphere. The more stuff you put into a small area, the more they crash into each other, and the more they change direction.
Now put a vacuum next to a pressurized atmosphere. Anything that moves INTO the vacuum will keep pushing moving forward. But if a ball tries to move OUT of the vacuum and into the atmosphere, its going to crash into all of the other balls that are bouncing around. Since it’s easier to move INTO the vacuum than to get back out, it looks like everything gets pulled in.
