Many people tell me that when I do Ghusl that I automatically have wadu and also I heard (I doubt it though) even if you jump into a swimming pool with the wadu intention you have wadu. Now I doubt these. Please tell me the correct answer and some proofs so I can explain it to others.
Yes, when you take a shower the ablution is involved in it. One of the sunnah aspects of showering is to make ablution, however, if no ablution is made the shower still would be valid still.
