Displaying random text (FML-like)

Hi everyone,

My website (https://www.uneseriedanecdotes.fr/) is mostly text. It's trivia from TV shows that I present in articles with bullet points for each show.

Now I would like to create a random section on my website where the trivia would be mixed and random, one trivia at a time. I would like to pick some trivia from all the shows and display it randomly, with the possibility to add an image per trivia.

Is the custom post type the solution? (even if I have to redo the articles). Or is there another solution?

Thank you for your help!
