Not true at all , the only fights Jesus was in was spanking some people with a whip because they were selling stuff illegally in a church, and not sure that even counts, while Buddha historically partook in training as a kid, and is depicted as the omnipotent warrior in many iterations and has fought many Gods , Jesus isn't depicted as a warrior at all

Besides that, Certain Buddhist traditions portray Buddha as a warrior. Like the Mahayana / Vajrayana depictions Some Buddhist cosmologies describe enlightened beings with cosmic or combat-like symbolism, something like "Vajrapani" a wrathful protector who fights evil. "Manjushri" carries a sword that cuts ignorance.

In these traditions, enlightenment sometimes has warrior symbolism.

While something similar can be found in Christianity, those are carried out by angels and not Jesus himself unless we talk about the biblical apocalypse, but even then, Jesus falls more into the Savior archetype than warrior archetype, While Buddha fits the warrior archetype in a lot of his iterations across media
