Wrong!
Darwin's four propositions
Within a given species, more individuals are produced by reproduction than can survive within the constraints (e.g. food supply) imposed by the species' environment.
Consequently, there is a struggle for existence, because of the disparity between the number of individuals produced by reproduction and the number that can survive.
Individuals within a species show variation; no two individuals are exactly alike (not even those we call 'identical' twins). Those with advantageous characters have a greater probability of survival, and therefore of reproducing, in the struggle for existence.
Individuals produce offspring that tend to resemble their parents (the principle of inheritance). Provided that the advantageous characters that promote survival are inherited by offspring, individuals possessing those characters will become more common in the population over successive generations because they are more likely than individuals not possessing those characters to survive and produce offspring in the next generation.
From the horse's mouth...
Owing to this struggle for life, any variation, however slight and from whatever cause proceeding, if it be in any degree profitable to an individual of any species, in its infinitely complex relations to other organic beings and to external nature, will tend to the preservation of that individual, and will generally be inherited by its offspring. The offspring, also, will thus have a better chance of surviving, for, of the many individuals of any species which are periodically born, but a small number can survive.Charles Darwin, On the Origin of Species, Chapter III: Struggle for existence
