Resources maybe, since you’d get sunlight from the star plus whatever material is caught in its orbit.
Fuel, no. You’d spend the exact same amount of fuel catching up to this star and eventually leaving its orbit as you’d spend just travelling across the universe alone at the same speed. You’d only save fuel if you used the star for a slight shot maneuver, where you steal a tiny amount of its energy to accelerate you, but this would preclude you spending the voyage in the orbit of this rogue star.

If your fuel is something that is inside the star (or star's orbit), and you have a means of extracting it, then you can use the star as a refueling point. You're right that using the star wouldn't require less fuel overall, but it could provide you access to extra fuel along the way.
