Those details from google are literally a collection of information that it pulls from various websites in which a user adds the information to describe them.
Example: Angelo is a gun-owner. The gun he owns is a .238 Summerfield Winchester. One site might put him as a "Gun-owner". This is equivalent of "racing driver". The other one might put him as a ".238 Summerfield Winchester" owner. This is the equivalent of "Formula 1 driver".
