The calculator also assume random selection. Don't trust statistics math too much. Even in acccounting where only arithmetic is being used, with legal auditing done yearly or quarterly basis, fraud is incredibly common (working in corporates for decades, they even termed it as massaging numbees by financial engineers). This kind of surveys without any audit and legal framework backing it, at 385 sampling is just inviting fraud. At least 2 to 3Mil needed and back by local election boards or local enforcement agencies. If this is done even in communist countries like China or Vietnam will still be way more legit than done in California or Oslo.
