Britain won, but it cost them pretty much everything. And while a lot of pride is connected to winning them, neither were wars Britain really had to fight.

WWI was caused by every European power thinking they could benefit from a war, leading to powder keg that blew up from a completely inconsequential event. For the British one of the motivations was getting Germany's African colonies that were in the way of building the Cape to Cairo Railway, which ended up never being completed anyways.

WWII at least had a clear villain. But it was a villain that made every indication that he didn't actually want to fight Britain. Maybe that was a ruse and Hitler would have attacked Britain after securing the continent, maybe it wasn't and a British and German empire could have coexisted. We will never know. What we do know is that fighting WWII required Britain to bleed its colonies dry, followed by losing most of them in the years after the war

I'm not going so far as saying Britain shouldn't have fought the world wars. At least WWII had justification beyond what can be seen on map. However without participation in those two wars Britain would have had a shot at continuing to be a wealthy empire
