I don’t think you’ll have much of a problem unless the pins are extremely close to the table but if that’s the case then you wouldn’t have room to even play pool. My pins are 10’ away so I’m never worried about it but I do have a window only 5’ away and a ball has never come close to hitting it. And I’ve had some people launch balls off the table pretty good but gravity takes hold very quickly so they don’t ever fly far.
