Broadly, being accurate is being close to the true answer, being precise is having low variability in the measurements. The wikipedia article has more detail.
I’d phrase it,
Precision is the reciprocal of the standard deviation of the estimate. Accuracy is the probability density of the estimate at the actual value.
