This statement is true. Probability samples are designed to be representative of the entire population, so even a small sample size can accurately reflect the characteristics of the larger population if they are selected randomly and with proper sampling techniques. The larger the sample size, the more accurate the estimate will be, but even a small sample size can provide reliable results.
