Annual/perennial isn’t a hard and fast distinction with plants, as it is often condition dependent.
In outdoor conditions where freezing occurs (most of the United States), outdoor petunias can be considered annuals as frost or near freezing temperatures will harm them. However they do not die after simply seeding.
However petunias moved indoors for the winter will generally survive for multiple years when kept out of cold weather (best to keep them above 50 degrees F). Petunias are in the nightshade family, and behave like you would expect if you have experience with members of the family.
At some point an indoor plant may decline or die for a variety of reasons (bacterial and fungal disease buildup can be an issue), however petunias are notable for being very easy to propagate via cuttings, as such they can be kept alive/multiplied indefinitely if you are willing to put in the work and research into how to care for them.

It should be noted that light.bio is perfectly fine with personally propagating them if you like, so long as you aren’t selling them: https://old.reddit.com/r/solarpunk/comments/1aw14j3/genetica...
