ML first or Data science first

I want to become an AI engineer.
So, i need all the basics steps to be done to complete it , like learning data science first or ML fist or DL .

They are all basically the same thing - applied statistics. Study up on your statistics and then focus on the one that interests you.

Note: to get a job in applied statistics, you’ll probably need an applicable graduate degree

Definitely ML first. The data science field is a vast field and ML is just a tool we use in data science.They may seem quite similar but under a microscope ,you ll see that the objectives of data science are different than that of machine learning.I guess you should get to the basics of ML first and then decide for yourself.
