The theory doesn't state that only a few in any generation can be winners. Your extrapolation is simply a poorly constructed strawman. Do you even know what the theory of evolution is?
"in every generation of every species a great many more individuals are born than can possibly survive; so that there is in consequence a perpetual battle for life going on among all the constituent individuals of any given generation."That's one example. Such quotes from evolutionists can be multiplied indefinitely.Romanes, Darwin and After Darwin
