There are mainly 2 types of tourist visa for Indian passport traveling to Thailand. 1) Visa on Arrival and 2) normal Tourist Visa
For Visa on Arrival, it's suitable for short term stay of less than 15 days. You don't have to apply visa in advance. Just fly to Thailand and apply at the Airport. In normal situation, the fees might also be waived during tourist seasons.
If you plan to stay longer than 15 days you have to apply for normal Tourist Visa via VFS in your region. This type of visa you have to apply in advance and it will grant you maximum 60 days continuous stay. This was the type which previously demands for 5 lakh statement during COVID period. Due to uncertain circumstances during pandamic, Thai authority wants to make sure you have sufficient funds if you have to stay in Thailand for a long time. Back then, it wasn't even guarantee that you could fly back to India easily.
I heard that the requirements might differ in different states. I only have the information based on my husband's experience in Chennai and what we were told. So pls check accordingly
