Maybe a serious math error? From your link[1]

> It is estimated that the amount of gold present in the entire universe is about 50 billion tons, with about one ounce for every 150 billion tons of Earth.

According to Alexander Budianto on quora[2] the earth is ~6.58310^21 tons ~ 710^21

710^21/(15010^9) / 10^9 = 46 billion

So that is ~46 billion ounces of gold on earth, rounded up 50 billion. Maybe that is where they obtained 50 billion from?
