Yep. Exactly. Most of the time, the Air will be Guest-centric, sometimes even despite proof that contradicts their word or msg. This has been seen many times.
A clever guest can use the right phrases, get a refund, etc. Good luck fighting that. Same thing goes for damages. You can even get de-listed. A guest can accuse you of threatening them, having hidden cameras, weapons, etc. You may have little or no recourse, and some bonehead in a call center will decide your fate.
As a landlord, not host, you have rights, deposits, contract and protection of law. Even still, you need to know the applicable law for your state. Most are reasonable. A few are protective of tenants.
Good luck!
