You are already ahead of the game because you sound humble and are willing to admit you don’t know things. Many of us (especially when starting out) act confident when we know little and coast for years gaining little knowledge.

Now that you have dabbled in a few languages and frameworks, try to focus on a cross-section of technologies that fulfill a job role. For example, understanding both ray tracing and database theory is not necessary for a single job role. Those are concepts for a graphics developer and a database analyst — two diametrically different roles. Pick a role that you want to shoot for and stick with it for awhile.
