Hello Nachito, and welcome to the forum.
No, that is absolutely wrong. To hear that word (and others) pronounced by native speakers of English, search for it in www.forvo.com.
The speed of pronunciation will never make it sound like "rovin".
I was told that the word ROWING, when said very fast, is pronounced something like "rovin" (sorry, I donīt know how to use the phonetic alphabet). Is this true? Thank you!

No.
Rowing would never sound like rovin when pronounced by native speakers of English. That said, I live in a place with a huge number of immigrants and plenty of them have trouble differentiating the sounds of the letters v and w. My wife is a case in point. After 45 years in the English-speaking part of Canada she still tends to mix up v and w sounds.
However, it is quite likely that the final 'g' might be dropped, especially with rapid speech. Some dialects tend to drop it even with slower speech.
