Look into MIT opencourseware — eg https://ocw.mit.edu/courses/6-0002-introduction-to-computational-thinking-and-data-science-fall-2016/. Or try a Google search "site:github.com data analysis full course"; this from OSSU seems good https://github.com/ossu/data-science. There are tons of free CS/data courses out there and there's no need to pay. You can go through the whole undergrad CS curriculum online free. Of all high paying industries, tech is by far the easiest to self-teach for free. You DM if you're not able to find something that works for you and we can discuss.
