Yes. The former is governed by commercial terms, and the latter is governed by consumer terms. That's different from your second question about model training

Yes. The former is governed by commercial terms, and the latter is governed by consumer terms. That's different from your second question about model training/retraining -- there is an answer to that questions elsewhere (but it is taken seriously and training data is also deleted upon deletion of the source data where it contains PII). I don't know this next part, but I suspect models use such vast amounts of data that any arbitrarily small deletion wouldn't have much impact.
