I want to undergo training in Phuket, I think to take any hot ticket, arrive in Phuket, be accommodated, undergo training, miss the departure date, after training + 7-10 days, take a ticket and fly back. Is there no violation on my part?

Sounds normal. Keep in mind 2 points. - when you fly, you will be given a visa-free stamp for 30 days, before this date (inclusive) you must leave the country - if you flew on a regular flight, then you must also fly on a regular flight (not a charter). And the fact that you will not miss the flight back on the ticket does not bother anyone, but it is better to warn the tour operator so that they do not look for you at the last moment.
