Do you think robots will take millions of jobs when they're put in different positions such as doctors or taxi drivers?

Yes, of course.

When you replace people with technologically advanced robots, it can disturb the economic factors. Although I don't agree with using robots as an every day, common thing, such as self-driving cars or like in the question, using robots as doctors. Technology is technology, it will always need updates and sometimes they break down or need repairs, so that could provide jobs for people; tech jobs that is. Not everybody is tech savvy though, but you learn. I still don't agree with it, but it is what it is.
