The Guardian received nearly 16 million photos during the Olympics (~62,500 per day).
It appears they invited photographers from wherever to submit their best photos and the Guardian posted a selection of their favourites.

These are all amazing photos that required planning (any professional photographer worth their salt will do significant planning for an event like this).
Given the very large number of photographers that submitted photos some would have been sooc jpegs and some would have been processed from raw. There is no exif in any of the "final cut" photos so I can't tell with certainty if they are sooc jpegs or not.
I suspect the photos of fast moving action were shot either in shutter priority with auto ISO or aperture priority with a minimum shutter speed set and auto ISO.
Fwiw, for fast action shots I normally use aperture priority with a minimum shutter speed set and auto ISO.
The composite soccer match shot is one of my favourites. Assuming there was no immediacy requirement to submit the final photo, given the photographer stated it took a long time to put together, I suspect the photographer would have shot raw to help minimise visible noise and processed the individual images and final composite in a layer driven app like Photoshop.
The composite is in my top 3 favourites. The final image is amazing given the challenge of blending the individual images into a seamless composite with so many elements.
The "Marchand underwater by Marko Durica (15-35mm, 1/200th sec, f/2.8, iso 2000)" photo is also amazing. I don't know if it was processed/edited in camera or in post but unfortunately the hands look a little too rubber or plastic like which detract from the image for me. They are an unfortunate eye-magnet for me.
"Floating surfer photo by Jérôme Brouillet" is my second favourite photo. It's a great capture. Almost certainly part of a burst sequence and talk about being at the right place at the right time for the photographer 😀.
My favourite photo is "Kayak cross by Tom Jenkins". Whether it's a sooc jpeg or processed from raw doesn't matter. It's a sensational photo capturing the action at the start of the race.
