Anyone can self sponsor themselves for visiting USA, Counselors and US Consulates understand that any individual working for couple of years and having an income more than approx 20,000 per month can sponsor themselves,
Also Indians usually have family support and therefore a visit can easily be sponsored in most cases.
The thing to take note of is, when you go for the US Visa Interview you have to make sure that your appearance, confidence, and communication is at its best which will give confidence to the counselor of your return.
