There's a difference, in that discussing the law and the implications of it are things we expect people to do constantly and not just by lawyers. For instance, I'm sure a lot of discussions in Wall Street around the contract Musk signed for Twitter were done by non-lawyers.
I do not think that such a disclaimer would help if we were talking about your, djoldman's, plea bargain negotiations.
In my experience, people generally believe that stating one isn't a doctor or lawyer protects against an accusation of practicing without a license.
