All models do this, they can't even answer what specific model they are

Could it be because Claude / ChatGPT are the most viral models and thus are more likely to be in the training set so when someone asks "Which AI are you?" the likeliness of Claude and ChatGPT being a reasonable answer is higher?

I think the implication is heavy distillation.

It has been observed again and again that ChatGPT and Claude would identify themselves as DeepSeek when asked in Chinese, through the API without a system prompt to solidify their identities. I don't think identity is a good evidence for distillation.

An alernative, it could also be the case that all of the model developers are using distillation to improve their models while crying do as I say, and not as I do.
