Congratulations on finally getting on a path to citizenship, that's really great to hear.
Yeah, in general the US immigration system discriminates between undocumented immigrants who (a) entered on a visa, and then never left versus (b) those who crossed the border illegally. People in category (a) can apply for green cards in many situations (e.g. marriage, or employment sponsorship after getting TPS) that those in (b) can't. Often times the wider public is not aware of this distinction.
