According to Wiki, she only served 4 years of that sentence.
"On 27 July 1989, Chamoy and seven accomplices were convicted of corporate fraud. She was sentenced to a total of 141,078 years or life imprisonment sentence in prison but Thai law at the time stated that the maximum sentence that could be served for fraud was 20 years. Her sentence was further reduced, twice, and she was released in 1993.[1]"
