Yes, Winter has trained longer. But if you go through an exam and got number 1, your spot as number 1 isn't going to change until the next exam comes up. Weiss got her number 1 - whether by birth, by trial or other reasons, but she is the indisputable official Heiress of the Schnee family.

That being said the father does seem to favor Winter over Weiss and has been doing sneaky things to thwart her (the exact content is spoilers, so that's all you need to know). It seems that they had a promise and Weiss had won, so he cannot change his stance or he'll lose face, but that doesn't mean he cannot play shadow hand and try to manipulate Weiss from the back. Winter's arrival at the Vytal Festival is probably a direct challenge from her father (controlling Winter), and if she loses to Winter then she'll have to reconsider her position as the Schnee Heiress again.

From Winter's point of view, it feels like not only she's being groomed as the Schnee heir (in the literal sense, considering her outfit and demeneor), Winter herself probably felt incredibly pressured to stay ahead of Weiss. She may be better than Weiss but that's a result of ten times the hardwork and Weiss feeling conflicted between reconciling their relationship and her unconsciously holding back (or think herself inferior) whenever she sees Winter one step ahead of her.

The White Trailer is a story about Weiss taking hold of her own destiny.
