Your CCNA understanding is correct, however to make life 'easier' for users many modern switches and NICs include an 'auto-crossover' feature so that if the wrong cable is inserted the port will automatically change mode so that the connection will work. This is great in theory, however I've found that not all devices impement it well, and in some cases will give degraded performance when in auto-crossover mode compared to when the 'correct' cable is used
