First of all, I don't think Sakura's parents have ever been shown in the Manga. So Kishi's depiction of them does not exist unless you include the Road to Ninja movie but the Manga is the main source of evidence.
Plus that does not look like Red-hair. Sakura has not been shown to posses high-chakra reserves and I doubt that she has a strong-life force either so that disqualifies her from being an Uzumaki or a Senju. I dont believe she posseses powerful chakra so that disqualifies her from being an Uchiha.
Kishi also said that when he created Sakura, he wanted to create a character that was a normal human being unlike chakra monsters like Naruto and Sasuke. Basically meaning someone not from a blessed clan.
