The word 'ballpark' is often used to talk about an approximate or rough estimate of something. For example, if someone asks you how much money you think you'll need for a trip, you might say "I'm not sure, but I think around $500 should be in the ballpark." The word 'ballpark' comes from baseball stadiums, where people would guess how far a home run was hit by an approximation in which the ball landed. So, if someone says "that's in the ballpark," it means that they think it's close to being accurate or correct, even if it's not exact.
