It’s not in the rules, but it makes sense. It also does have rules about taking an automatic 10 for low DC stuff, which you usually only do if even a roll of 1 would succeed so it gives a good trade off having nat 1s be a failure even in skill checks when the player opts to roll instead of taking a 10.
