What I mean is I use it to get the links to those sources. Like when you use Wikipedia as a jumping off point. I don’t think we’re at the point yet where we have the problem Wikipedia sometimes has that the sources used sometimes themselves just cite Wikipedia.
I read an interesting article a few years ago about the Wikipedia source problem. It did a dive into how sources that seem legitimate on Wikipedia can and up citing sources that are less so. They were able to trace back the citations to Wikipedia itself. So no, they’re not always real sources.
Which is why you read the page it has linked for you as a source. Unless you’re trying to say it full on generates a page for you.
