No, it's never too late to learn Data Science. It's a popular domain today and will be for a long time now. Because in this digital era, no developments are possible without properly extracting insights from data. If you wish to learn Data Science today, there could be no better time than today.

But the thing which you should remember is that Data Science is a vast field. So you must learn and master all the different tools and techniques to become a qualified professional in the field of Data Science.
