This is why I've come to this conclusion that winnings that are unexpected are more exciting than winning that have been predetermined/expected.

I don't think anybody gamblers without expecting to win. It will be preferable to spend money on other types of entertainment than to place bets on games you are not expecting to win. However, there are some cases, especially in sports bets, when you have lost hope of winning a bet. Maybe the team you placed a bet on is losing by a wide margin. Later, the team puts up a good performance and wins, making you win the bet. Such unexpected wins are more exciting. It's like recovering something you thought you had lost.
