Released birds are just a numbers game, as long as they are disease free and relatively healthy. Like anything else in life it is a giant bell curve, some at the upper end are going to survive no matter what happens in the environment. Some at the lower end wouldn't survive if they were fed by hand daily. If the conditions are right with weather and predators the middle of the curve will do okay. As someone mentioned, all pheasants in the US started from released birds. Heck we even have a viable population of pheasants in Homer descended from escapees and they made it under the watchful eyes of hundreds of Bald eagles.
