I saw what you meant in Chapter 130, where Giyu says that Sabito lost his family to Demons just like him, but I think it's too vague to conclude specifically that his parents were killed by Demons (he could be referring to his sister as his 'family,' since his parents had died beforehand). I can't say for sure if the databook information is 100% accurate either as it's a fan translation, but I believe it's trustworthy enough since I think it'd be difficult to mistranslate death by illness compared to death by Demons.
