"So whqt does it mean? I could say I am a potential prime minister, because an am a political person, or a potential supermodel, because I am a female. . Both would be stupid things to say."
No more stupid than what you have been saying about entire groups of people not being potential abusers.
You introduced the idea of the "potential abuser" to this discussion by insisting that it was not OK to say that ten year old boys were potential abusers.
But some 10 year old boys are abusers. We know that.
And so obviously there is the potential for 10 year old boys to abuse.
So a unknown 10 year old boy might be abusive.
It's a possibility. That's not really deniable.
That doesn't mean all 10 year d boys are abusers. Or most. Or many.
But it does mean that there is the potential that a 10 year old boy might be abusive.
Your examples are not equivalent.
If you said that no mothers were potential prime ministers because you were not.
Or that a certain woman you had never met was not a potential supermodel because she could not possibly be beautiful enough, despite you never having seen her.
That would be closer to the kinds of statements you were making earlier about the lack of potential for abusiveness in 10 year old boys.
