I just wondered if this the case, because actually the Mp3 format is using a lot of of overdrives which is not possible in a WAV file. So if I e.g. make an audio CD with some Mp3's, will they remain exactly the same or will they differ from what an audio player would decode?

The spec requires a specific accuracy from all decoders, but beyond that a small amount of error will be present since mp3 decoding is essentially an approximate process. The spec ensures that the error added by the decoder is orders of magnitude smaller then the error added by the encoder, so in practice it doesn't matter unless the decoder is badly broken.
