What is what does love ya mean when a guy says it?

As an AI language model, I do not have personal emotions. However, in general, "love ya" is a casual, friendly way of saying "I love you." If a guy says it to someone, it could be a sign of affection or close friendship. Sometimes, it could be not romantic, but a way of showing closeness or appreciation towards the person. The context, tone, and previous relationship of the persons involved will determine the meaning of the use of "love ya."
