Yes. The immigration system in the US is complicated. There's a diversity quota based on the nation you were born in and there's a lottery involved. The other way is the Employment-Based Green Card.
For a person like the OP who is of Indian origin, they are unable to go through the diversity based lottery and have to go through the employment based one. Depending on the subcategory you apply in, your wait times could be as long as 10 years.
On a personal note, my opinion is that the US immigration also places too much importance on the nation of origin. In my case for example, I've spent over 20 years of my life in Canada and am a Canadian Citizen, but if I wanted to immigrate to the US, my nation of origin (where I was born) would be the deciding factor on what category I could apply to.
