Yes, you are mistaken. British Indians are about 1.4 milion, British Pakistani are about 1.2 million(2011 Census). You lot always think others outnumber you if the ratio is close to 1:1.
Asian or Asian British: Indian | 1,451,862 | 2.3% |
Asian or Asian British: Pakistani | 1,174,983 | 1.9% |
Asian or Asian British: Bangladeshi | 451,529 | 0.7% |
Asian or Asian British: Chinese | 433,150 | 0.7% |
Asian or Asian British: Other Asian | 861,815 | 1.4% |
So just to re-iterate the point again, no one is outnumbering you anywhere. Chinese maybe in some parts of the world but they don't have the urgency(not in the past and wont be in the future) to leave their country as much as the Indians do.
