Yeah but because Wikipedia articles, to an extent, ephemeral it is good practise to use the sources at the bottom of the article as your source, rather than the Wikipedia article itself. It makes finding the origin of the information easier.
If it is something more permanent like a paper or a published article, then that doesn’t suffer from the same issues
