Why Vitality are still nto qualgied for champs?

I'm genuinely confused, why are vitality still not qualified? Aren't they already top 3, because fnatic qualified through champion points?

It works the other way around. Top 3 at playoffs are seed's 1 2 and 3 for champions. From the other 8 teams, whoever has the most points qualifies through points as the 4th seed.

Rn KC is the leader in points of the non qualified teams which means if VIT don't make top 3, KC will be going as the 4th seed

Because Fnatic can also be top 3. And so can Fut and TH. So if FNC, TH and FUT are top 3 (and not VIT). KC qualifies due to having more champs points. So VIT have to win 1 more match (either this one, or in loser's bracket), to actually qualify.
