Can you get 99 in every stat in Elden Ring?

I'm curious, is it actually possible to attain a perfect score of 99 in every statistic within the game Elden Ring? As an avid gamer, I've heard rumors of players striving for this goal, but I'm wondering if the mechanics of the game truly allow for such an achievement. Do the game's leveling systems, resource gathering, and other factors make it feasible to max out every attribute, or is this just a pipe dream for the most dedicated of players?
