Another more basic example is gravity. We have a statistical intuition of gravity, we depend on it being there and acting in a consistent way for almost everything in physics. But we don't have an accurate understanding of how gravity works or why it's there. We have theories, but nothing proven. But it's so easy to prove gravity's properties (on Earth) by consistent results with experimentation, that it's literally a science project in every elementary school.
