Amazon indeed has a much smaller share than the East India Company had, but I think you may have exaggerated a bit with "at least 2 orders of magnitude". It should have been "at least an order of magnitude".
• 2019 global trade was $19.0 trillion [1]
• 2019 US retail was $4.85 trillion [2].
• Amazon 2019 US retail was $0.22 trillion [3].
• Amazon 2019 global retail was $0.35 trillion [4].
I'm using 2019 because the US retail Amazon data at Statista.com [3] requires an account to view the graph but the visible text on the page includes the 2019 numbers.
That puts half of global trade at 43.2x Amazon US retail (1.6 orders of magnitude) and 27x Amazon total global retail (1.4 orders of magnitude).

One intended effect of Amazon’s PR strategy is to create a sense of momentum about their business. Obviously that is working if people are comparing it to the East India company.
