To start with to fight vs old WB they needed their full power: fleet admiral and Garp, 3 admirals, all VA, elite marines (weaker ones were not called since they would have been useless due to haki), 7 warlordsa, an army of PX and the advantage of fighting at home (fortified positions with cannons, barrier to stop people etc) whioe WB had his crew woth 4 ships + all his allies.
Now we have Kaido and his crew and all his allies most likely (the numbers who usually ate not around) since there is the banquet then there is BM with a fraction of his crew woth at least a YC2 with her and several veterans, after this we have also Orochi and his samurais who will fight with Kaido and on the top of that you want to add the supposed 5th emperor, Kidd, Law and crews plus minks.
The navy would need the same level of power displayed at Marineford and would still lose. Not for nothinflg Garp said that if the Rocks reformed there was nothing they could do and this is the former Rocks + Wano, minks, Luffy, Kidd, Law.. Way too much for the navy.
