I would suggest going to university. Anything else is a waste of time if you're looking for employment. The only exception would be if you're an employee (programmer) of a large firm that's willing to train you and put you in a position to use your skills. But if that was the case you wouldn't be here. Don't spend months of your time self-training because nobody will hire you without hard qualifications. Also ML is a very large and diverse field, with many different sub-categories. What you learn from online courses depends on the course. Most of them are essentially just training videos that teach programmers how to use a certain library. If you really want to learn ML, browse for graduate programmes in universities you can attend. If you don't have an undergraduate degree, go get one. If you only want to learn ML as a hobby with no prospects of getting employed, try studying from various online courses (ie on MIT or coursera etc).
