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?

Well they have but it was done on purpose.
why not accidentally? well space is big and asteroids are small and far between.
asteroid belts for example do not look like what they look like on tv/ the movies they’re very far apart.
Interestingly Probes are pelted with small bits of stuff, plasma, gasses, radiation etc a lot of these things are too small to do any damage real or in the case of radiation the electronics are hardened against it.
To collect material for future examination they used areogel for sample capture via the Stardust probe. This probe collected both cosmic dust and particles from the tail of the comet Wild 2 and returned it to earth for analysis.
