The odds are not in Naruto's favor at first. Kaguya is extremely powerful. But Naruto has a never - give - up attitude. He could start by using his shadow clones to confuse Kaguya and then find an opening to attack.
If we consider Naruto's growth throughout the series, he does have a chance. He has the power of the Nine - Tails, his Sage Mode, and his strong will. However, Kaguya has vast and almost unbeatable powers like her ability to create dimensions. Naruto would need to be very creative in his fighting strategy, perhaps using his Rasengan in a way he has never done before to counter Kaguya's attacks.
In this fanfiction scenario, Naruto's odds also depend on his emotional state. If he can keep his cool and not let Kaguya's power intimidate him, he stands a better chance. He might also call upon the memories of his past battles and the lessons he learned from his mentors like Jiraiya and Kakashi. This could help him come up with a plan to defeat Kaguya on his own.
