I get that some foundations do have sinking issues, but how does having a foundation help? If the foundation is poured and solidifies, what stops the weight of the house from immediately sinking/tilting the foundation?

A house “sinking” doesn’t mean the same thing as like what happens when you drop a marble in a puddle. It means that the different materials expand and shift and sag. If you’ve ever had a wooden door that’s harder to open when it’s humid, you’ve experienced this. A foundation gives it a hard, rigid platform to keep it from shifting too much. And depending on where you live it’s also a major support for keeping your house from completely collapsing in an earthquake or being tossed by a tornado with your inside. If a house were going to just sink into the mud or sand, than that is not a suitable place to build a house.
Not all houses have foundations. Sometimes you’ll see a manufactured home, or some cabin that’s propped up in a platform or some cinder blocks. Those houses don’t just sink into the ground, but they also won’t last as long or be as safe in.
