When the Lannister King realized the battle was lost he retreated and knelt to Aegon. He could just as easily have been proud and arrogant and died in the battle; probably wiping out the Lannisters. So while it couldve gone better for the Lannisters throughout history, it could also have gone a lot worse. It's the Baratheon name that has claim to the throne, not the Lannister name.
