It depends on perspective. If you look into karma, it only holds for the perspective of sequences of lifetimes, or a couple of lifetimes being interwoven by karmic ties. What karma is is also very mystical, but not unthinkable physically speaking. Ie. gene expressions can flip during a lifetime, thus our genes hold memories lasting for at least a couple of generations. So ancestral karma is also a concept, but hard to research of course.
From a holistic and wider perspective of wholeness, everything may be said to be predestined. From a spiritual perspective, it's about how everything is set up in order to have certain experiences and maybe "lessons". Mathematically, if you have all the variables, everything that may happen can be solved by calculation, however that is done on the cosmic scales.
If the idiot is guided by a higher mind, then there's no room for "luck" on the grandest scales, but it will look like luck to the person, as a unique and individual experience.
