Original Note:
The math is not correct. Going many generations back, individuals will appear repeatedly on your family tree at different places. At 10 generations, your total number of ancestors is almost certainly less than the number in the post. This is referred to as pedigree collapse. https://www.hewittgenealogyservices.com/blog/what-is-pedigree-collapse
