Yes, hope you have cleaned them. Otherwise the draw is too much for the corrosion to carry. You need to clean the battery posts, then take battery in for a new one, then buy new cables. (that's a joke).
Did you get a click? or starter rotated? or what. If you want help without 50 posts, describe what is happening. Your post, which are typical of inexperienced persons, are not definitive. Get a new battery and get new cables and things will start to fall in place. We can't diagnose the patient until there is a heartbeat. The motor won't start from a glow. This is not to spend your money foolishly but would be done on an old truck as normal maintenance after sitting. Batteries won't tolerate sitting, they dry out and when asked to rejuvenate, it's Kings X.
