If you think about it a bit, it should be obvious that nothing is being trained on your results. You're not being exploited for training data, because computers are already better at identifying traffic lights from street view images than you are.
The image recognition task has not changed for a very long time. How many captchas do you think have been solved by users in the last 5 years, all the same kind of recognition problems on the same kind of data? Trillions? It would be way past any kind of diminishing returns for this task to get more labels. If there was value there, they would have at least switched to a different kind of task.
In addition to that they're trying to get sites to move to Recaptcha v3, which does not have the user solve any kind of. Why would that be if the answers had any kind of value?
The fundamental problem with using captchas for training is that it devalues their value as a tool for security, since it sets up conflicting incentives. And the latter is what Google is selling. (Yes, selling. Recaptcha Enterprise costs money to use at scale, and the list price seems to be $1 / 1000 calls). The people paying for that service are using it to block attackers and let good users through, not to challenge the good users just to get some more labeling data from them.
