Read the documentation. I think the docs.python.org documentation is very good.
https://docs.python.org/3/library/random.html
Once an element is selected by random.sample() it cannot be selected again. random.choices() can select the same element multiple times. A side effect of this is that random.choices() can return a list that is larger than population (k > len(population)), but random.sample() will raise an exception.

Quote:random.choices(population, weights=None, *, cum_weights=None, k=1)
Return a k sized list of elements chosen from the population with replacement. If the population is empty, raises IndexError.
Quote:random.sample(population, k, *, counts=None)
Return a k length list of unique elements chosen from the population sequence or set. Used for random sampling without replacement.
