Strawman argument but I'll try to explain. If we had only 3 countries then 50% would be from Lithuania and 50% from Rest. That is equal and fair because it doesn't discriminate against anything about those two countries. Mass emigration (to anywhere) is not something we should promote as a good thing. If we take all of the top people in the country that leaves the country poorer and worse off than if we did nothing at all.
The point is just because a place like India has a huge population shouldn't prevent or make it more difficult for people to immigrate from Australia, Europe, Africa, Japan, South Korea, or any less populated countries. The same goes with China. What gives China and India other than population alone the upper hand? Are they somehow more valuable than someone from Japan? Are the more valuable than people throughout Africa?
If you want unbiased immigration you treat everything equal. From within those pools you can argue who is more worth the green card via a merit system that can be scrutinized against those peers within the same country. By your standard India and China would dominate the immigrant population and leave less well off countries with an even worse chance for economic prosperity.
