It depends on how long you wait and where you are bitten. The further a bite is from the brain, the longer you have to live, and the larger a mammal is, the longer it takes for the rabies to develop (so, for example, a whale bitten on the tail will take almost a decade for the rabies to develop and kill it).
However, even then, the shots aren’t just a one-time ordeal. You need to find a way to get a shot a day for I think twenty or so days before the rabies affects the brain. Remember that these are vaccines. There are no cures, you can only race against time to prevent it (or you can vaccinate yourself before there is any reason to fear, which is common in certain occupations).
Unless your circumstances are generous, like if you got bitten in a lucky spot with a lenient amount of rabies and then rushed immediately to the hospital, your chances of surviving are next to zero. The reason bat bites mean certain death is because they always bite on the neck, with people who don’t know the signature thorn-like feeling of a bat bite not realizing they were bitten fast enough to react in time (so yeah, if you feel a thorny sensation while walking at night, call someone immediately).
