These numbers alone don't tell the story, as other posters have alluded to.
Yes, PC1 have explained that. But today's players faced better returners, slower surface.
Karlovic holds the record for most aces per match in 2007(better than Goran's best year in 1996), and he faced tougher condition/returners.
