Skeleton screens – do we display them in case of lack of content or lower amount of content than suggested in skeleton screens lay out?

Currently, we add skeleton screens with a progress bar while the page is loading with data (in a data-driven platform). I'm wondering what in the case where after loading time no data is available or ie. just one card is available not a few cards - like skeleton card suggested. Do we still use skeleton cards in this case? what's the usual flow?
