It’s actually both; they are using the data for ML:
Captcha if you can: how you’ve been training AI for years without realising it
Capchas don’t work like that.
They way they work is they read everything about the movements that lead up to the choice, the actual choice has little to do with the analysis.

That’s how websites use them to determine if you are a bot or not.
However, the companies that ever so nicely provide the captcha technology, and never ending supply of unique pictures… They don’t do that just because they love paying for the bandwidth and hosting all of this stuff for free. They use your clicks to train their AIs in image identification.
