Very much depends on the modifier, though. Like in Baldur's Gate 3 they do crit fails/successes which is what made me think of this. But say my character is a level 20 wizard with an essentially superhuman mastery of Arcana. So a bonus of +12 to arcana and is presented with a rune that needs to be identified:

Under the crit fail/success system, this genius Archmagus with a knowledge of Arcana in the same ballpark as Mystra herself has a 5% chance of not knowing what the fuck that rune does instead of whatever small percentage rolling a minimum of 13 would get you on that particular skill challenege. If this dude rolled the lowest he can roll, it is and should still be treated as pretty damn good.

And it's ultimately up to the DM, of course, but RAW matters too
