Yes, you are wrong. By Law, Visa Exempt Entry additionally requires: i. Confirmed Ticket out of Thailand. ii. 10,000 Baht/person (20,000 Baht/family). But, rarely are visitors from the major countries (USA, UK, AU, Western Europe) queried by Immig. Officers for above. But, they could. HOWEVER, most major Airlines will ask for proof of onwards flight, because it is the Airlines that would be "on the hook" to return the person if denied entry.
