UDP isn't unreliable in the sense that it fails to do its job -- it's unreliable in the same way a convertible is "un-dry". Well, no, it's unreliable in the sense that if I ordered a package online, the courier may get lost on the way and never come with my package, and then I have to order it again if I want it delivered, and then hope that this time it actually does, in that case, it kind of does fail to do its job if you want things to be delivered.
