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.
I think this makes a lot of sense, a near miss is still a loss and it has the capability of making you start chasing if you are not disciplined enough. Just like you said luck is all that matters in the end and gamblers should do better when it comes to accepting their losses and just move on. If you can't accept whatever outcome you get it means that you don't know what it means to be a gambler. Losses are inveitable
