The vast majority of USB sticks are lost, not attacks, the vast majority of USB keys handed to you are handed to you in good faith, not as attacks.

That doesn't mean there are no attacks.

So prudence is adviced in either case, on the off chance that the one that you have is a bad one. Ditto for anything else that you stick into a USB port.

That webcam plugged into your computer, are you sure the mike isn't on all the time and that the driver doesn't pass your speech during the day out in compressed and encrypted form to some server farm at night ;)

Just like bareback sex with partners who remain monogamous for the duration of your relationship, repeatedly sticking the same USB device into your computer is a lot less risky than sticking a wide variety of USB devices of unknown provenance into your computer...
