I dont think we should a term like "near-miss" in gambling because it is a loss in simple terms. You dont get a consolation prize for having "nearly missed" you have lost your wager.
If you were playing the soccer match, then things would be different and near missed can be justified but because you are gambling on the outcome, it is either win or lose the bet.
So take as losses, and add them to the loss list that will help you understand that your luck is what matters in the end.
Those who say they almost managed to win are most likely just looking for excuses for their failures. It might be harder to deal with losses when you miss just one event in a big parlay. In that case it really feels like you were very close to winning. It is a different story if several or even half of the events did not win because then there is nothing to regret. When only one fails it seems like you were right on the edge of victory. But in gambling there is no such thing as almost winning. Every bet has clear conditions and you either win or you lose, there is no other option. You can also make a cash out but that is a completely different thing.
