Parametric hypothesis tests do not assume that the sample size must be greater than 30. This is a general guideline for when the Central Limit Theorem kicks in, suggesting that the sampling distribution of the mean is approximately normal for large sample sizes, but it is not a strict assumption of all parametric tests.
