Orochimaru dedicated most of his adult life to research, not ninja training. Jiraiya traveled the world and gathered intel for Konoha.

None of them were busy advancing their techniques. Yeah. What a waste of potential. Except for Orochimaru. At least he came up with sick and twisted methods to extend his lifespan, even though he got his ass spanked like a bitch by a teenage Itachi. Tsunade probably spent a good proportion of her years running away from tomato ketchup, mistaking it for human blood. Sigh.
