If the Senju had that much, Uchiha by your logic, would of just copied it all so that point is mute. Actually the implication is that yes, their arsenal was big enough that the Uchiha couldn't copy it all. The Senju simply didn't specialize in any style of jutsu, so if a certain uchiha would face a different Senju, they would have to analyze it all from scratch. Contrast clans like the Ino-Shika-Cho where the clans all use similar jutsu, or the Uchiha themselves (genjutsu and fire jutsu, mostly). Or, say, the Sarutobi clan and their fire jutsu.
