I would have taken the udacity courses on machine learning by now, but the stated requirement is a strong familiarity with Probability Theory, Linear Algebra and Statistics. I wouldn’t describe my familiarity as strong, that will take a few more years.
I think you’re overestimating these requirements. I haven’t taken the Udacity courses, but I did well in my classes on AI and machine learning in university, and I wouldn’t describe my background in stats or linear algebra as strong—more “fair to conversant”.
They’re both quite central to the field and you’ll end up using them a lot, but you don’t need to know them in much depth. If you can calculate posteriors and find the inverse of a matrix, you’re probably fine; more complicated stuff will come up occasionally, but I’d expect a refresher when it does.
