How many of us are honestly bad at our jobs?

I had a plumber out yesterday to change some taps. He arrived, told be it would be hard to install these particular taps even though they were the same I had before, created a leak, apparently fixed the leak, then told be my brand new taps were faulty. (Credit that he decided not to charge me for not delivering a service, nor compensate me for the side effect of mild damage to the house.) I don't know much about plumbing but I know it when I see it and plumbing was not happening.

It got me wondering, how many of us are basically quite bad at our jobs? How many of your colleagues are?

I'm awesome and my colleagues are too! Go Team!
I'm amazing, but my colleagues are kinda sketchy.
Honestly. I have no idea what I am doing. But some of my colleagues are amazing!
We are all of us in the gutter. No work gets done. Even management doesn't know what we are meant to be doing. But they have been paying us for so long it would reflect poorly on them to ask.
Something else
