My dad bought a new betta? help?

He thought it would survive in a tiny bowl and it can't. Unfortunately it needs so many things. I look up online and it needs a heater, bloodworms brine shrimp... So does it need a filter?(a store employee at petsmart said no but its yes for a filter online..). How do you cycle? What else do I need for a betta home? How much will every item cost?
