I want to speed up the loading speed of my WordPress website. These are different terms or are they the same? If they are different, what do you recommend applying?

They are different.
On the one hand, every web browser has its own cache; This is especially useful for not repeatedly downloading relatively large resources such as images, javascript libraries, css style sheets - and also, but less importantly, html pages.
If you have a site in Wordpress, normally, there is not much to do on this side, although there are some plugins that allow finer adjustments.
On the other hand, there are (there may be) several levels of caches on the server (and also in the middle way). In Wordpress, the most relevant are the WP super cache caches that are responsible for saving the html code of the pages (dynamic) that Wordpress arms and returns. What is saved in such a case is mainly the time to dynamically assemble the page (which usually involves searching the database). This saves CPU and improves the speed of response, in the case of repeated queries to the same pages. But it does not influence the volume transferred between server and browser.
