Virtually everything you have said is totally inaccurate. All you're doing is stating your opinion, which is unsupported by citations or logic.
They also were outnumbered at Delhi, but they didn't win because of technological superiority. By all accounts, the army of Gwalior was just as well-equipped and trained, even led by French generals. The French won many times while being outnumbered in the Naopleonic wars (look up Auerstedt). Same for the Swedes during the Great Northern war. What does that prove?
Swedes often fought and won while outnumbered. So did the French. The French helped train and support the Maratha, therefore Maratha was just as advanced as the British.
This is a very silly use of the transitive property, which totally ignores empirical facts.
3,000 British sepoys beat 17,000 Maratha troops at Delhi in 1803. You say not because of superior MIL Tech, but you don't account at all for this Maratha failure.
I will say that when a smaller army defeats a larger army regularly, it usually indicates a superior level of training, technology or doctrine. This translates, in game, to a higher MIL Tech. I would consider that Sweden had a higher MIL Tech than Russia around 1700.
Not to mention you are factually wrong in many instances.
The British were defeated by the Mughals
When? In 1764, 40,000 Mughals were decisively defeated by 7,000 British.

Please cite a conflict between the Mughal Empire and the British Empire where the Mughals were triumphant. And most relevantly, shows that the Mughals had a qualitative military parity with Europeans.
The British were defeated by the Maratha whilst they were completely free (had wrapped up their war with Mysore before).
False. The First Anglo-Maratha War (1775 - 1783) was fought concurrent with the American Revolutionary war. And the British placed higher priority on fighting the American Revolutionaries at the time.
The British basically won by not even fighting the Bengal army (which was overwhelming in numbers), but by buying the loyalty of the Bengal generals.
This is false. Your bias causes you to ignore the fact that 18,000 of the most elite Bengal troops (which were not bribed) attempted to engage 3,000 British troops and through superior doctrine, organization and administration, were routed.
The inverse, Mughals or Bengali buying the loyalty of British Generals, is absurd and highlights that the professionalism of the British Army was far above that of their contemporary Indian opponents.
you seem to lack a lot of knowledge with regards to the history of India, so I feel your opinion is highly tainted by ignorance.
