FNATIC total kills more than BBL?

How is it possible for a team to have more kills than the winning team when it was a 5 round difference? Im confused. FNC had 77. BBL had 70. But it was 13-8 to BBL. Did they refuse to defuse the bomb or what? (Missed the map so idk what happened. Gonna watch it rn)

yeah, lost a lot of rounds to time
I think the comp didn't work, I feel like double dome + tejo on abyss isn't good

fnc lost to spike a lot
