That's a bad reading. Even if everyone in a household with a gun owner have access to guns, that would mean 33% of households implies exactly 33% of people if gun ownership is distributed among households with no bias by household size. It doesn't imply more than 33% of people unless gun owning households are larger than non-gun-owning households.
