I applaud the replies I have read so far and only wished I could give answers to any questions that may have been asked. I researched further on this topic and here's a snippet of what I could gather(link attached):
'There are several different types of Trifectas available to punters so make sure you find the right structure to work with your betting strategy.
A Straight Trifecta is the most affordable of all Trifectas but it is also the hardest to win. Select the horses that finish 1st, 2nd, and 3rd by making only one selection for each position.
A Boxed Trifecta, on the other hand, allows the punter to make any number of selections (limited to field size) with their runners being able to finish in any order.
Flexi Trifectas enable punters to take a percentage of the full unit of their bet, allowing them to outlay only as much as they can afford; it also means they can throw on bets they might otherwise have been unable to afford.'

These animals unlike the way our soccer stars are followed up during training, off training, and during match games, were also much talked about and observed during these times. I would very much like to take my chances at trying out a trifecta bet online, if I have the opportunity to. Perhaps for fun, and luck.
