Super late reply. Basically no.

It only increases his debuff resist by 100%, it doesn't make him immune (Example of debuff immune are effects like Xuanzang Sanzang 3rd skill)

Each servant and enemy have their own natural debuff resistance

Effects that cause debuff also have a success chance

Some computation takes place that compares the debuff success chance and debuff resistance to get the final probability that the debuff is applied. Let's say its as simple subtraction, a debuff with 100% chance to be applied to a target with 110% debuff resist, the debuff has -10% chance to be applied (so basically negated). Another example is maybe a debuff with 180% chance to be applied to a target with 130% debuff resist, the debuff has 50% chance to be applied. Take note that is only an example, I have no idea how it is actually computed.

As described in the older posts below, some effects have 200% chance to apply debuffs, some even have guaranteed chance to be applied. This CE is situational, useful for fights where enemies that apply debuffs "normally" during combat, but you are better using debuff immune for fights were enemies apply debuffs at specific times (e.g. when you break an HP bar. Better to use a 1 turn debuff immune to counter that, and use a different CE for Gramps)
