[Masters in ML] Want to clarify if my undergrad credits meet the course criteria

[mad_world]

I am very keen to apply to the masters program in machine learning at cmu. However, I am unclear if my background is fit to get through the cmu admission criteria.

My background:

1. I have an undergrad degree in Economics. The course covered Statistics, linear algebra and calculus extensively.
2. While I have done coding on my job, I do not have coursework experience/credits on programming.

Want to clarify the following:

1. The minimum criteria at cmu mentions this- "Incoming students should have good analytic skills and a strong aptitude for mathematics, statistics, and programming." Would it suffice if I do online courses related to programming to enhance my profile?
2. Also, what are the kind of topics that I should be covering under the online courses?
3. Are there any online courses that you can recommend?
4. Are there other universities that would be better suited to my background?
