am I roma?

My family is from poland but my mom immigrated with me as a little kid to Germany and I was raised here. My grandma said that the father of my mom (who we don’t have any contact with at all) was ,Cygan‘ and she definitely has the features (olive skin , brown hair, brown eyes) and I do too, that’s why I stand out from the rest of the family who is blonde and blue eyed . Also she said my dad might be ,Cygan‘ too but she didn’t really know the family and he also very much looks like it (I don’t have any contact with him at all, and haven’t since I was 2 years old).

I don’t want to claim anything , but my maternal grandfather definitely is Romani like my grandma said but I don’t know about my dads family but it seems plausible ? I have looked into family history but there is literally not a single thing I could find. I‘m interested in Romani culture and history and don‘t mean any disrespect !
