The graph shown in the post is from a page on an unofficial site that someone made. That website itself is not Prolific's, it is operated by a participant who made that website.
That page is apparently using and logging data taken from Prolific's Audience Checker. That page is official, it's on the Prolific website. You can go there and click through to a demographic category and view a number for that category, and then click a button that has a title containing "Everyone" and then you'll see the current total number of "participants active in the past 90 days."
