To me these numbers show that Amazon have managed to compete reasonably favourably with the BBC, which is famous for being really good at making TV shows, within 5 years of starting to make their own content, they've built a platform that people are willing to use to watch that content, and they've developed a model that audiences are willing to pay for. That's huge.
Slightly OT: YouTube will be big in „live plus same day“ this year. Boxing match of KSI vs Joe Weller [1] drew 1.6 million live viewers and 16 Million on the (official) released video after. I'd estimate the announced fight of KSI vs Logan Paul in August to yield closer to 5 or up to 10 million live viewers with a massive „same day watching“ after.
Sure the content is not for everyone but might be a glimpse at what a younger generation prefers.

The most recent Academy Awards show was the lowest rated in a decade, and it got 26 million people in what's called "live plus same day" which includes for people watching on their DVR's shortly after.
That's 26 million people in just a few hours for one show in one country. Amazon's five million came from 19 shows, "airing" across an entire year, in however many countries have Amazon Video.
If you were to break it down by same-day viewership, Amazon's ratings are lower than a local news show in a very small market.
I'm not criticizing Amazon, at all. I'm a paying subscriber and think it, Netflix, and similar services are a better vision of the future than what the broadcast and cable nets have put together. But it's way too early to tout the death of the broadcast industry, as so many like to do.
Also, The Grand Tour is awesome.
