Some people just can’t accept being wrong even when presented with facts.

_______________
BHUMIPOL ALULYADEJ, REX.
Given on the 30th day of April, B.E. 2522;
Being the 34th Year of the Present reign.
His Majesty King Bhumibol Adulyadej is graciously pleased to proclaim that:
Whereas it is deemed expedient to have the law on the Tourism Authority of Thailand;
Be it, therefore, enacted by the King, by and with the advice and consent of the National Legislative Assembly acting as the National Assembly as follows:

Which part of LAW don’t you get buddy. The “A” in TAT is Authority not a lobby group. They don’t set immigration laws of course. But you were asking about formal/legal definition of tourist. This is defined by TAT under law.
