Shift to data analytics


I am into retail banking business in a reputed Public Bank. I want to do a course in data science and machine learning. I have a great deal of intrest in the same and am very good with numbers. I have done Masters in Economics in 2011 and I have 7 year of experience in banking. I want to know that based on my profile should I go for the course. And would my previous experience be considered if i switch my job after doing the course or would I be considered as a fresher?
