There is no doubt that having an art background and being able to draw can help enormously when using a 3d app , but it's not essential and you can learn Maya and achieve whatever you want but it requires effort and dedication.
You can learn the interface pretty quickly but modeling , texturing and animation require practice and then some more paratice oh and then some more paractice.
To be honest I don't think we ever stop learning, there is always some new way to achieve a desired result or unique way to use a tool and that is apart from new tools or features released with updates.
If you plan to model characters then it would be a good idea to learn human anatomy or at least get a basic knowledge of it, this too can be learned without having to go to art school but just by reading and gathering reference material.
Working with reference is essential when modeling ect, take time to collect it and study it before starting to model and most of all use it in Maya so you can keep preportion.
Maya can be frustrating at times but can also be very rewarding so don't give up .Most of all it is supposed to be fun so if you are struggling at any time just take a break and come back to it later with fresh eyes.
12 months down the road you will probably wonder why you even asked this question ... good luck with the learning.
