No hair and looks like there is liquid on it

I’m going to try to get a better pic soon sorry

That looks to be under the forelimb and there are a few possibilities.   It could be an abscess, a walled-off ball of infection introduced by a bite-wound or other dirty penetrating injury.  I can't rule out a an over-licked skin problem, foreign body or cancer of the lymph-node bursting out.  At its most benign, this hole will merit treatment - cat-appropriate pain releif if nothing else (NEVER human pain meds), and perhaps some physical way of stopping the licking.  This should be prescribed by a vet who can assess the patient in context.  Please will you let us know how you get on?

I think you should go to the hospital and see a veterinarian because if you look at the skin condition, it looks like it has an infection.
