Every player has to learn the basic maths. The faster you do this, the sooner you will notice you're results have improved.
After a while, you might notice you don't need to do those maths in most hands, it becomes an internal reaction, and not a calculation anymore. That's when you can start to learn some new maths, which in time will also become an internal reaction.
Rinse and repeat, rinse and repeat.
I did not learn those basics as fast as I might have. I wasn't horribly bad at them as I had a pretty good understanding of probabilities from College, but poker has specific situations with specific math needed to help solve those situations. Actually, those situations don't occur all that often, but when they do they usually result in bigger pots.
So, again I say that the sooner you learn those basics, the sooner you will see improved results.
You don't need to be LeChef (Casino Royal) to see good results via poker.
