Kodak began introducing automated, daylight processing as early as the first decade of the 20th century. I'd venture that more than half of the BW film photogs who've ever existed never set foot in a darkroom. Of those that did, 75% never set foot in a darkroom after high school or college. 99+% of color film photographers have never been in a color darkroom. For those that have 99% never did again after college. The vast majority of serious photogs and pros use photo labs, and it's been that way since Eastman introduced film in 1888.
