Yes, even though Jon was not born yet, he would NORMALLY be considered the rightful heir to the throne.

HOWEVER, the Mad King changed the line of succession so that Viserys was the heir. He, as king, has the right to do that as Westeros has a absolute monarchy - which means the kings has all the power - so no laws that prevent him from doing that. Many kings in history have changed their line of succession.

Also, only the Northeners will believe Bran’s vision - and even then most will be sceptical as his powers are mythical even to them. The Southeners will not believe it as they do not believe in the Faith of the Old Gods. The Northeners also hate the Targaryens and distrust them. They already wanted to replace Jon as King in the North with Sansa in Season 7, but they didn’t because he was Eddard Stark’s son. So, when they find out that Jon isn’t even their be;over lord’s son, they’ll most likely pronounce Sansa Queen and abandon Jon.

And actually, there is more proof that Daenerys is like Aragorn than Jon. In fact, whenever GRRM talks about Aragorn, he links it back to Daenerys. Yes, Jon also has some similarities but Daenerys, like Aragorn, is from a noble family but lives enstranged of thr throne. Both have a corrupt ancestor as a father and need to prove themselves to other to get rid of that assumption that their corrupt too. On the other hand, Jon, though seen as a bastard, was still Edward Stark’s son and so he got treated with more respect because of his lineage.
