If the sample is not representative of the population, then the characteristics
of the sample are not the characteristics of the population.
Example:
If I want to estimate the percentage of the population that are men, and my
sample is the school's football team, my estimate would be that 100% of the
population is comprised of men. What went wrong with my survey ? Simple.
The football team is not a representative sample of the population, at least
not as regards gender.
It is important for a sample to be representative, so that the whole population's view is counted, and not biased by one particular group within the population.
Because without representative sample, your results will not be valid.

A representative sample is crucial because it accurately reflects the characteristics of the larger population, allowing for valid inferences and generalizations. If a sample is biased or unrepresentative, the results may lead to incorrect conclusions and undermine the reliability of the research. This is particularly important in studies that inform policy decisions, marketing strategies, or scientific research, where flawed data can have significant consequences. Ultimately, a representative sample enhances the credibility and applicability of the findings.
When a sample is representative of a population, it is said to be a "probability sample" or simply a "representative sample." This means that the characteristics of the sample accurately reflect those of the larger population, allowing for valid inferences and generalizations. Such samples are essential in statistical analysis to ensure the findings can be applied to the entire population.

To generalize results from the sample population to the target population.
Many statistical statements for a population which are based on a sample are not valid if the sample is not representative.
Because without representative sample, your results will not be valid.
A sample is any subset of the total population. A representative sample is one that is chosen so that its characteristics are similar to that of the population.

A representative sample is a randomly selected subset of the population.
A simple random sample.

A sample that accurately reflects the characteristics of the population as a whole
It is called a representative sample.
