If someone is into a specific kink but keeps it totally fictional it is not directly equatable to expressing that kink in real life. As the move to expressing it in real life requires additional actions, behaviors, thoughts, and often times compounding kinks such as a fetish for domination/bdsm/etc.
So someone that looks at animated underaged characters is not, necessarily, a pedophile.
That being said, if you enjoy and draw sexual gratification from drawings of underaged females, and specifically because they are underaged (not just because boobs are boobs/drawn like they’re adults) then yes you have tendencies that would lean toward pedophilic interests. And there is no denying that. Otherwise, their age would be irrelevant to your interests.
It would be like enjoying apple pie, baked apples, and apple crumbles but never liking raw apples. You can specify that you only like apples in certain ways, but it would be totally wrong to say that you are in no way a fan of apples and not interested in eating them.
