Incorrect.

Every Servant can be a Berserker. Remember that Zouken had Arondight as catalyst, but chose to summon Lancelot as Berserker instead of Saber to compensate Kariya's low capabilities. So all Servants, when summoned under ME summoning spell (like Lancelot case), is Berserker.

The berserk history is for 'fit-and-proper-test' to Mad Enhancement. If one had berserk history, its easier for one to got Mad Enhancement on high rank (Lu Bu and Heracles) or can be summoned as Berserker by default (no need ME summoning spell).

Given her NP already grant access to Osaka Castle, Yodo-dono's Berserker status most likely come from time after Tokugawa Ieyasu act resulting on both her husband and son death.
