Those numbers are rough approximations - a query goes through deep pipelines of selecting pages, ranking and refining them in several stepsto achieve the best possible precision-recall trade-off and optimize for clicking through to the results and not come back. It’s all optimized to show you the top 10 results, everything else is an afterthought. Part of this is because hardly anyone scroll to after link 10 anyway.
