Oh cmon.
I’ve worked in Australia, the UK, many parts of Asia, South America on big and very low budget shows.
It’s not just some exclusive enclave in Hollywood. Those are universal truths. The scale changes perhaps. But it’s not just Hollywood centric. I’m fact I’d argue Arri are even more dominant in other non US markets.

Australia is "first world". In the second and third, the sets are smaller and less refined, the sound is recorded exclusively in post, the shot framing is ... well, let's just say, very Roger Corman'esque, et cetera, et cetera.
A year or so ago, an FB friend posted an article about "French films not to be missed". Many of them were romantic comedies, a genre that I enjoy. So, I sampled a few of them online. Then looked up whatever info I could and here what I had found. Their budgets are in the $6M-$10M range. The look is fully professional but the sets are a lot smaller, the takes are a lot longer, the shot framing contains far fewer closeups and more medium and wides. Overall, they're much closer in feel to the Hallmark flicks one sees on Lifetime than to a Hollywood theatrical release.
I also have friends or friends of friends who worked in television in the Soviet and post-Soviet markets. Their budgets were in the "late night TV on Channel 56 in Podunk" range. Some couldn't even tell their news anchors not to wear a blue business suit in front of a blue screen because that's the only business suit their TV anchor had. And they had to rely on an outdated equipment, that didn't even include a teleprompter, so anchors had to read off a typed sheet of paper and look down most of the time. And, of course, they didn't immediately upgrade to ARRI. As recently as 2015-17, BMD Cinema Camera was a preferred choice for many productions. Alexa was solely for the big budget theatrical projects and those presented a minuscule portion of the overall number of aired content hours.
PS. Bollywood is technically "first world' in terms of the sheer box office volume. Popular movies exceed $10M in gross, which is a huge amount in the country where an average income is $1,800/y in nominal terms. I assume that, if they do use ARRI cameras, they have a solid used selection that are certified by ARRI.
