Don’t lose hope - it’s completely achievable writing production ready code by learning from books and other online resources. I’m sure many members here are living proof of that 
Professionally produced books and courses are invaluable imo.
The trick however is getting the order of learning material right.
I’ve started to put a prescription of what I think newcomers could do here: What is your recommended order of reading Elixir books in 2019? hopefully I (and others) will add more thoughts as we progress through the material ourselves. By the end of it you should be relatively competent, even if your programming experience is limited to begin with.
Why not start it now and see how you get on?

I also agree that you will most likely find you are continually learning… that’s not a bad thing tho and I’m sure it eases over time
