Does everything you drink contain pee? (sh.itjust.works)

I think I heard a long time ago someone say like "every glass of water contains water molecules from the pee of benjamin franklin" or something to illustrate the scale of how many atoms there are in things. Is this true? Has so much pee hit all water sources that everything you drink from anywhere was once pee?

Times that by 8 billions people and that many water molecules have been in any person pee currently alive.

Add in a another billion+ or so people for people who were alive before now and you've got even more waterolecules which have been in people's pee.

Then add in all of the other mammals and vertebrates on earth and you've got MORE water molecules which have been in pee before.

That's a lot of pee.
