We don't need them to catch up with Marvel, we need them to make descent movies that best represents their characters, shared universe or not.
DC also needs to figure out their voice and what their strengths are as opposed to Marvel's. The Boys success hinges on them going places Marvel wouldn't while at the same time parodying Marvel.
Even if they were making Marvel money, $53 billion would still be a crazy amount. For perspective Marvel had $20 billion in box office after Endgame.
Actually, a lot of VFX artists have started speaking out about Marvel and their tight deadlines, going for the lowest bidder and changing their minds at the last minute. Phase 4 has had a lot of complaints about bad VFX and people have talked about not knowing where it's all headed. Top Gun 2 is breaking domestic box records whilst Dr Strange 2 and Thor 4 didn't perform as well as most people were hoping they would. It honestly makes me nervous about KD and SW. Too many people are acting like it's a forgone conclusion that Marvel will nail it like they did the Infinity Saga, that's a recipe for failure. I hope they do nail it but I'm not expecting any of these movies to land on the date they've announced without experiencing any delays.
