As well as being a compulsive womanizer, Chico had a lifelong gambling habit. His favorite gambling pursuits were card games, horse racing, dog racing, and various sports betting. His addiction cost him millions of dollars by his own account. When an interviewer in the late 1930s asked him how much money he had lost from gambling, he answered, "Find out how much money Harpo's got. That's how much I've lost." Gummo Marx, in an interview years after Chico's death, said: "Chico's favorite people were actors who gambled, producers who gambled, and women who screwed." Referring to Chico's love life, George Jessel quipped, "Chico didn't button his fly until he was seventy."
