While out gravel or mountain biking or doing touring, yes. You're really stupid if you don't carry some basic first aid when in remote area's.
Short cycles around the city/commuting? No need.
I had to use a couple of bandages for a friend who faceplanted on a downhill.
Had to use some gauze when I fucked me hand off a tree once too. Nothing serious. But it makes the difference between cycling home with an active bleed down your legs/onto your handlebars vs comfortably cycling.
