Does a reading of the last paragraph in the novel suggest that OBrien or Winston won?

The last paragraph of George Orwell's "1984" suggests that Winston ultimately succumbs to the Party's ideology and control, indicating that O'Brien, as a representative of the Party, has triumphed. Winston's acceptance of love for Big Brother signifies his complete indoctrination and loss of individuality. Therefore, rather than a battle between the two characters, the conclusion underscores the overwhelming power of the Party over the individual.
