"No, I'm not a horse better. Every once in a while somebody will give me a sure thing and of course it's not"

M. Emmet Walsh's quote implies that he is not foolproof and does not constantly make the right choices. He is suggesting that, although he is not a "horse much better," or someone who bets on horses, he is sometimes lured by individuals providing him "sure things." He is suggesting that these sure things are not always trustworthy which he has actually been incorrect in the past. This quote shows the idea that no one is ideal and that even the most experienced people can make errors. It also recommends that it is important to be cautious when making decisions, as even the most seemingly sure things can be incorrect. Ultimately, this quote functions as a tip that it is very important to be familiar with the threats related to any decision and to be mindful of the prospective repercussions.
