It’s not the quantity of the knowledge, but the quality, and, even more, what you do with it.
Personally I wasn’t frum my whole life and my knowledge is rather limited – particulary gemoro-wise. But that doesn’t bother me, since I have plenty of knowledge (though I always strive to learn more) and I have sufficient knowledge to be able to find whatever I want to find.
Wisdom compensates quite well for lack of knowledge, and wisdom is something you have, or don’t have.
