Do Reports contain results of past searches or are they only a reference to a saved search query?

I'm new to Splunk and I find Splunk reports confusing.

In other SIEMS a report is the results of a previously ran query. However, it seems to be that reports are saved search queries without results of previous runs. So, when I click a report name it seems to be rerunning the query and now showing results of a previous run.

Are my assumptions & understand of reports correct?

It's most common for a report to run a query and display the results.  It is possible, however, to create a report that displays the results of a previously-run saved search.
