Poland produces itself over 70% of the primary energy it uses. So it's not much import-dependent at all. But yes, since most of the energy it produces is coal, it imports about 2/3 of the natural gas it uses, and most of that, about 1/2 of the total use, from Russia. Anyways this isn't a big deal since it has sea gasification terminals, and gas market is going global because U.S. needs ways to export lots of cheap natural gas they have. Right now LNG is cheaper than Russian gas.
