Comparing background checks to gun ownership is like comparing apples to flat chested women. Background checks aren't only for firearm ownership, but also explosives. It even says so on the website you just linked:

The mission of the NICS Section is to enhance national security and public safety by providing the timely and accurate determination of a person’s eligibility to possess firearms and/or explosives in accordance with federal law.


Then you would have to factor in the amount of people who were denied, and the amount of people who passed a background check who never bought a firearm or bought a firearm and then sold it (or had it taken away).
