How to deepen your knowledge about Oracle?

You can train yourself with many books and get an advantage over your competitors by developing a set of skills highly sought throughout the world. Niels Bohr saw an expert as "a person who has found out by his own painful experience all the mistakes that one can make in a very narrow field". So why not you? Be an expert!
To that aim, the first reference book I would suggest is "Oracle Database 11g The Complete Reference (Oracle Press)Oracle Database 11g The Complete Reference" by Kevin Loney. This internationally recognized Oracle expert was named Consultant of the Year by ORACLE Magazine in 2002. Also be aware that the 12c Oracle version is available on here : Oracle Database 12c The Complete Reference (Oracle Press).
In addition to that, let me suggest "OCP Oracle Certified Professional on Oracle 12c Certification Kit" as further reading in order to improve your skills and pass your first level certification.
