Is it just dumb luck that our probes (e.g. Juno, Voyager I, Voyager 2) never collide with even the smallest rocks in space? Is space in our solar system so void that the odds of a collision are so low? Does NASA (and other global space programs) have details about natural debris throughout our solar system that they can avoid collisions through navigation?

Space is really big. Like, OMG big. Think if you put all space probes ever made in one place. They would probably fit in your house. Now think of the distances in space. You could fit 13 trillion Earths in the area formed by a sphere the size of Earth’s orbit around the sun.
That’s a lot of space for a few Earth probes and a smattering of asteroids.
