There are requirements but essentially, yes.
There are requirements that you will want to check, should be on the site I sent you.
Basically:
$$$$
Onward travel
Place to stay
I *think* you will need to have at least 600USD (20,000 baht).
Another concern, if you come on visa exemption, is if the airlines will allow you to board. They may not allow you on the plane if you don't have the requirements.
Many people come on visa exemption, its not a big deal but you want to make sure you have everything you need, to assure your trip goes smoothly.
Currently, there is a matter of Thai Pass. It is also require and different from visa. The Thai pass requires you have insurance, place to stay, onward travel. You go through that process 2 or 3 weeks before you come to thailand. The requirements may change by the time you actually come.
