Dumb Clerics who don't know anything about other religions but their own is absolutely a thing.
Same with a charismatic Barbarian being better at intimidation than another equally strong one devoid of any kind of presence.
And the smart scholarly druid having better knowledge of nature than an equally powerful but less intelligent Druid.
The stats are there to differentiate members of the same class within their group.
Edit: that's also why rolling for stats can be better. With point buy all barbarians will dump cha and int but with a roll you can get that charismatic Barbarian who can be a leader.
