First of all I would like to point out that when it comes to quantum physics, I have very poor knowledge so please excuse me if I misuse some words to describe what I mean.
My question is based on Isaac Arthur's example in this video. To save you time, he is giving an example to show that if something is possible, it will happen no matter how improbable it is. His example is about a mad scientist who vaporizes himself in a box and I quote him: "yet at the same time, so to speak, at some time and place in the multiverse, random quantum chances assemble that box and out steps a clone of the doctor or one close enough to make no difference"
In a previous example in the same video he says: "there is a universe right now where you flicked on your light switch and a random chunk of furniture in your house turned into a bunch of gold ingots"
Disregarding the multiverse and the many worlds hypotheses now as the question is not about them, and disregarding the exact details of the examples above to prevent the violation of mass and energy and momentum conservation, could quantum physics have any probability (even if extremely low) to change say trillions of atoms from one element to another?
In this article, the author answers it clearly with a NO saying: "The uncertainty principle applies only to individual quantum objects and small collections of quantum objects. When trillions of quantum objects are involved, the uncertainty goes completely away"
So which of those arguments is the correct one?
