If the number is in the billions you're not going to experience each of those websites anyway - you'd run out of time in your lifetime. I suspect (it was introduced before I started, and re-introduced after I left) that it's there to remind users of the work that software performs on their behalf, much like how TurboTax says "$X in taxes saved" or Brave says "9 hours saved blocking ads" or your brokerage says "Total profit: $X". Users tend to forget this, and just assume that they're entitled to the world where the product exists.
