How easy is it to learn STATA?

Hello there, I am a medical student and have learned that research is important as a med student. Some of the research I do needs stats some basic stats like descriptive statistics P values, Kaplan Meier curves etc and then you have the more advanced ones needed for meta analyses. Should I buy STATA and do some courses on Coursera would that be enough to learn? How long would it take and is it doable?

Thanks.
