Universal healthcare does not mean "free healthcare". What it means is that all people have equal access to healthcare, the kind that would otherwise be provided by everyone having private healthcare insurance, such as what would need to happen in the US. The intent is that this would be more affordable for the average person than not having a universal healthcare system.
Of course, affordability is not a guarantee for all treatments, regardless of which healthcare system you agree with. It seems this is the problem for the Kim family. Even in a universal healthcare system, things like chemotherapy and cancer surgery might still cost too much for people who earn below living-wage.
