When I drop my phone in the toilet, or dive with my phone in my pocket, or spill water on my notebook, what happens to it? Why does it stop working? Is rice any better than just letting it dry?

No one has answered the rice question. Rice is hygroscopic, meaning it greedily absorbs water.
If you take a shower without the bathroom fan on, the whole room becomes very humid. In the same way, drying out an electronic device in a sealed baggy won’t work because the moisture will make humidity and then the water will stop evaporating. The rice provides a place for the water to go as it slowly evaporated from the item you want to dry. This keeps the air dry and makes the item dry out more quickly. The idea is to use a lot of rice, because more rice can greedily gobble up more water faster. And you want to dry the object out as fast as possible.
