For a sample to accurately reflect a large population, it must be representative. This means that the sample is similar in important characteristics (such as age, gender, socioeconomic status) to the larger population, and therefore can be used to make accurate inferences about the population as a whole. Statistically significant refers to whether the differences observed in the sample are likely to have occurred by chance or not, but does not necessarily guarantee representativeness. Relevance to the population is important, but not as important as representativeness. Non-probabilistic sampling methods (such as convenience or snowball sampling) can result in biased or unrepresentative samples, so probabilistic sampling is generally preferred.
