A publicly traded US corporation is by law first and foremost about making money for the stockholders, that's why the mind always races to nefarious (well, OK, money making rather than plainly nefarious) scenarios first.
However, there's no direct dollar path from an organic search result to Google income. It's an indirect path:
Useful SERPs = More Users -- and that leads to more revenue
Otherwise the implication is that Google gets money directly from Amazon for organic listings or conversions from organic listings, and that is not the way things work.
