is one piece episode 903 filler?

Luffy continues his pushing battle with Urashima. Though originally at a standstill, they eventually push each other back and struggle to stay in the arena.

They push themselves back up and Luffy declares an official sumo match. Luffy dodges Urashima's hand slaps, then attempts to lift Urashima up and throw him out of the ring.

At one point, Urashima throws him out of the ring, but he manages to launch himself back in. Eventually, Urashima resorts to using illegal moves in attempt to defeat him.

Holed'em hears about the sumo match. He does not intervene, as he is focusing on torturing Tama.
