A light year is a distance, not a time. It's the distance light travels in one year. At 3 x 10^8 m/s, it is something like 6 trillion miles.
The stars, even the nearest ones (not our own sun) are so distant that their light takes years to get here. We can say how far away they are in terms of how many years, so that we don't have to deal with ridiculous numbers of miles!

Yes, light travels at 300,000 km/sec. In a year, it will travel
300000 X 365 X 24 X 3600 = 94608000 followed by 5 more zeroes kilometers. That is 1 light year and stars are atleast 4 or more light years away from us.
