Yes, if you had a list of all 8,000,000,000 people in the world and went to visit 385 truly randomly selected from that list and didn't leave until you got an answer, yes the theory says that would be a reasonably trustworthy sample. But that theory is useless in practice, when the efficacy of the survey is entirely determined by the sampling bias. Here we have a survey of a few thousand people who had internet access and were on whatever websites promoted this survey and chose to click through the survey and had their votes counted by whatever "spam filtering" logic was used, and multiplied by whatever "population correction factor" was selected, and they're trying to somehow pass it off as "85% of People". Its bogus through and through.
