Still doesn't make them gods even if its just a title that has to be given.Vegeta and Goku are already gods. Vegeta has 3 god forms and Goku only has 2. The actual gods, kaioshins and hakkaishins, don't even know UI. So knowing UI can't be what makes Goku "pretty close to being a god". So that paragraph makes no sense.
Zamasu wasn't a official god either, he just labeled himself one.
