No, that's false. At the very least, all residents are covered, regardless of their working status in Austria, Spain, Portugal, Croatia, Czech Republic, Denmark, Finland, Iceland, Luxembourg, Norway, Romania, Serbia, and Sweden.

In Romania you need to be employed to have the public health insurance. There is a long list of other exceptions, but being an entrepreneur who just started a company and doesn't have income is not one of them.

Add the Netherlands. Healthcare insurance is mandatory.

The subject is about mobility of workforce.

The standard is almost always résidence, not work status. So if you move to that country from inside the EU and thus get recognized as a resident you get these benefits, sometimes after a period of time.

add Germany to that list.

Which countries is that exactly? I know for a fact Finland and Spain have free healthcare for the unemployed.

Is that for everyone or the Unemployed that you have to register to be a part of with terms & conditions? Because Estonia also gives healthcare to the Unemployed, but you have to be signed up at the job agency and I think you have to have had a job recently. If you don't fulfill some other criteria you can be taken off the list.

For everyone in Finland at least, don't know for Spain...

What? I think citation needed here.

As far as I am aware, healthcare in most EU States is universal and not dependent on employment.

Sure you can get private healthcare through employment, but the state systems is there for everyone if they need it.

I think they probably mean if you move countries, for example it took a few months for me to get setup with Iceland’s health service when I moved here.

But there’s easy schemes to retain cover like EHIC. https://ec.europa.eu/social/main.jsp?catId=559
