The lore is actually unclear on that. Most seem to agree that Lucifer is a fallen angel, but it’s never so much as suggested in the source material that Satan is Lucifer. Lucifer is actually only mentioned one single time, in an old testament verse. The other dead kings are making fun of the king of Babylon for failing to defeat God and dying himself. As the king of Babylon is dying, the other dead kings say he has “fallen from heaven” and call him Lucifer. It seems implied that Lucifer and/or the king of Babylon are being compared to the sun, the “morning star”, and I think many have interpreted this as to mean Lucifer was an angel that tried to shine brighter than God and this was cast out of heaven. But it seems like most of the modern depictions of Lucifer have no basis in biblical canon. It’s all people trying to extrapolate from one single time the name Lucifer was mentioned while dead kings make fun of a dying king.
Lucifer in the Old Testament testament is the king of Babylon I believe in context.
The symbology of a star falling from heaven fits with allegories of stars as kings/rulers in many places in the Bible.
As for satan being a fallen angel that’s a little more substantiated
Luke 10:17-18
Fiction tends to get more from the apocrypha and similar spurces… things like the rebellion, Lilith etc. More meat on the bones when you want to write an interesting character.

The “morning star” referred in the bible is not the sun. They had no idea the sun was even a star.
The firsts mentions of the sun being a star was in 500BC and the Greek that said it was exiled as heretic for even saying something like that. The old testament predates that for millennia.
The morning star and the evening star, at a different time of the year, are the planet Venus. Which was the brightest “star”.

Yes, you are absolutely right. I totally had a brain fart on that.
