Firstly there is a typo, it would be Machine Learning. See both the courses are good but if you see the recent developments in AI and Machine Learning then you will find a lot of application in Neural networking which have applications in Robotics and Data Mining. Now if you have Data Science then you get a edge to the industry in the R&D and modelling of data sectors. so both the fields have a lot of employability, and both of the graduates works in hand in hand. So if you wish to go for the courses then you can choose any of the two and you will be able to work in any sector. Now if you are more inclined towards Robotics then you will have a more interest in AI and ML and for you it would be better to choose AI&ML.
