Of course not? The idea would be a government (who already has your age data for example) will allow you to create a signed message and the platform you are verifying your age to doesn't know who you are, what age you are but that you are of age

And also, crucially, that the government does not get to know what platforms you are visiting. (the process goes: you get a certificate for certain facts, then your 'ID wallet' generates a ZKP itself that can prove that you have a certificate of any subset of those facts, and neither the certificate issuer nor the receiver of that proof can link that to anything but those facts, even if they collude)
