The graphic is mostly true.
Arouch arrived at Auschwitz in the summer of 1943 and fought about 200 times (usually 3-round fights) between then and 17 January 1945 when the camp was evacuated.
Not all the fights were against other prisoners, some were against German soldiers.
A 19 February 1990 People magazine interview quotes Arouch as saying:
“The loser would be badly weakened,” he says. “And the Nazis shot the weak.”
The fights were not 100% forced on Arouch's part, as Arouch is quoted in a 18 December 1989 New York Times article:
"...commander - I remember his name as Hans ... I tell the commander's interpreter - I am arrogant now - 'If you have a good boxer, bring him to me and I can show my stuff.' "
upon which they brought him a prisoner from Czechoslovakia to fight.
The Nazis used a combination of rewards and threat of death to force the prisoners to fight.
Additionally, there is some dispute whether or not the boxer was in fact Jacques Razon rather than Arouch. See footnote 33 of page 251 in Greece--a Jewish History
