What information would you have to suggest that Sasakibe has always had that position. In fact there is no information that suggest that statement to be true. Shunsui and Ukitake have not been captains since the Gotei 13 was founded, they are only the first to graduate the academy to become captains. Unohana has been a captain longer then them. It only states he knew his bankai before they knew theirs. That only means anything in accomplishment doesnt mean he was in his position at the time. It also goes without saying that Hitsugaya was unheard of 100 years ago. It clear he isnt that old. If he grew up around Momo and is a bit younger then her and she went to school with Renji, Rukia and Kira. Then that much is obvious. He is also the youngest captain and newest so that would mean that he is under 100 years old.
