David “Devilfish” Ulliott -- a British poker player who got famous on "Late Night Poker" -- died Monday following a battle with colon cancer. He was 61.
Ulliott's son announced he "died peacefully surrounded by his loved ones."
Ulliott was just diagnosed in February, and doctors didn't give him great odds ... saying it was really just a matter of time.
He amassed $4,364,305 in tournament earnings and is survived by his wife Anpaktita and their eight children.
