Offspring formed due to sexual reproduction have better chances of survival. Why? Is this statement always true?

Answer- Yes, this statement is always true. 

Explanation: Offspring formed due to sexual reproduction have better chances of survival because sexual reproduction exhibit variations and these variations are important for survival of species. Offspring which do not exhibit variations and are exact copies of their parent (as in asexual reproduction) occupy the same niche or place in the ecosystem. The populations tends to get wiped out if this area gets altered due to natural or manmade causes. However under such conditions individuals with variations can colonise other habitats and survive.
