Haha no problem at all..
Learning computer science through an university will indeed help you a lot, but there are a lot of great programmers that left university or even never got to an university for the topic they are working on!
In an university you don't learn deep knowledge for each topic, but just general knowledge.
This is common for all the different scientific branches and for Computer science which is very wide and has many different topics to work on and where things change day after day very fast, this is of an even greater degree.
No-one is perfect and there always is a way of writing code better, faster, "cheaper" etc.
The thing is: You can learn if you want too.
It might take you more time to get to a level that more professionals are at now, but it's not impossible.
Wish you good luck, just start simple!
