Treblinka II was an extermination camp. Its sole purpose was to kill Jews, and most of them were gassed as soon as possible after arrival. A very small number of new arrivals were 'selected' to help with the extermination process by burying the corpses. It was not a labor camp.
Treblinka II was the main extermination camp after Auschwitz II (Birkenau). An estimated 850,000 Jews were slaughtered there and only about 40-45 survived.
The Treblinka extermination camp was established in 1942 during World War II.
Treblinka II was an extermination camp and only about 40 people survived - that is, were still alive at the end of World War 2 in Europe. None of them is particularly famous.

The number of survivors of Treblinka II (the extermination camp) still alive at the end of World War 2 is given in the Wikipedia article on Treblinka as 40 (forty). (Compare this with the usual estimate of at least 850,000 victims slaughtered). Please see the link below. In addition, there was an older labor camp, Treblinka I, which was mainly intended for non-Jewish Poles who did not "cooperate" with the Nazis. It was a concentration camp (not an extermination camp) and had more survivors. Apparently some prisoners from this camp were drafted for various tasks at Treblinka II, but otherwise the two camps were distinct and separate.
Treblinka extermination camp was created in 1942.
Treblinka extermination camp ended in 1943.
Treblikna I was a very harsh Nazi forced labour camp. Treblinka II was a Nazi extermination camp, in operation in 1942-43. An estimated 850,000 victims were murdered there. It had the second highest death toll, after Auschwitz. Both camps were built and run by the SS.
