I just can’t comprehend how there are still spaces where water does not enter even when submerged

Air isn’t “emptiness” it takes up space. If you try to push air underwater, it will want to float up because it’s less dense than the water. However, if you put something in the way that keeps the air from floating up then it gets stuck under the water, its still something that takes up space though, so it pushes against the water thats trying to flow into the space that the air is sitting in until it pushes hard enough to stop the water from coming in at all. You can test this by taking a glass cup, turning it upside down, and pushing it underwater. The air in the cup can’t float up because the cup is in the way, so it stays inside the cup and pushes against the water that is trying to flow in and keeps the water out.
