the ins does not call to anybody and is not a "green card" lottery,it is a visa lottery and of course you need yo enter with and special form, fill it up, mail it,etc.,etc. does mean if you got a call saying you won a green car it is fake or a fraud

The US Diversity Immigrant Visa program is also know as the Green Card Lottery because only a number of those that apply will receive a Green Card. Each year 55,000 people receive Green Cards.
Applying for the Green Card lottery does not directly impact your current visa status. Winning the lottery and obtaining a Green Card would allow you to live and work permanently in the United States, potentially leading to a change in your visa status. However, simply applying for the lottery does not affect your current visa status.

No, you do not have to be a resident to win the lottery.
The US government has a form of 'green card lottery' where a small number of people from a large number of applicants, are able to get a green card. Beware though, because there is a common email scam where people are told they have won a green card - without them ever applying, of course - trying to trick them into sending money for processing fees and such. A real green card lottery winner would be informed by postal mail in most cases - but anyone who hasn't applied should automatically be suspicious.
