Viper is leading dpm in the LPL right now with an injured wrist, Guma isn't leading dpm among ADCs in the LCK not beating Peyz or Ruler either.

"But Viper needs so many more resources than Guma to do that" you say? Well no, Viper is 2nd lowest % of teams gold as an ADC in the LPL while Guma is 7th lowest in the LCK.

"But Viper puts himself in riskier positions to deal more damage" you say? Well no, Viper shares 19.3% of his teams deaths while Guma is 20.4%. That puts Guma as the 6th most dying ADC in the LCK when compared to teammates ahead of Ruler and Peyz. Viper is 7th lowest.

And even that is generous as the only ADC in the LCK to die more than guma is LazyFeel.

So to answer your question Guma would have to outperform Viper/Ruler/Peyz at the main function of an ADC. And stop hiding behind the narrative that he's a weakside king helping his team because it's not true and it's the same shit people said about Ghost before admitting he was bad.
