False
If you think Zoro's stalling attack here (the first one of his that actually does damage to Kaido) is doing more damage than the cumulative amount of Damage Luffy has done up until now then we'll have to wait and see the scans to see if Kaido truly gets fucked up or not.
But up until this chapter Luffy has been carrying everyone else on the roof in both a combat setup perspective and individual damage perspective. Unless you think Zoro's failed group attack Onigiri (only attack that hit Kaido up until this chapter) did more damage than Luffy's red roc (that made him bleed), his kong rifle (that Kaido conceded damaged him) and his kong gattling that presumably did more damage than his kong rifle did .
Even this chapter Zoro is sneak attacking Kaido while Luffy takes the agro, if you want to get as petty as a zorotard.
