If the sun is constantly emitting energy, does that mean it is also constantly losing mass? If so, why is it said that the sun will eventually grow in size?

Yes, at the rate of roughly one lunar mass every million years, not including the particles spewed off as solar wind. Overall this is insignificant compared to the total mass of the sun. The sun is expected to increase in volume, decreasing the overall density, which isn't really related to the loss of mass.
