How to throw a successful party with college aged kids?

Im 21 and im throwing a house party and im kinda scared it might be a bust. Im getting a 16 gal keg, making jello shots, having food, but idk what to do about more drinks. Im throwing this party alone so i dont wanna spend a ton of money alone on liquor. But i dont want the party to turn out lame because there wasnt enough drinks, i put bring your own bottle on the event but i mean how many ppl really do that? So what could i do to even things out? Will a keg and jello shots be enough? Idk what to do
