It could be ad-blockers, though. And I want to emphasize a point you mentioned briefly: it very much depends on your target audience. An anecdote from several years ago, around with IE was still the plurality of traffic on most sites but no longer the majority. Two web properties run by the same company, with different audiences. On one of them, IE did not crack the Top 5 in browsers, and was actually outnumbered by Opera. On another, the entire Top 5 browsers were different versions of IE, and Chrome and Firefox combined were less popular than IE6, IE5.5, and AOL's browser (which apparently was a reskinned IE7).
The moral of the story is, what's true for everyone may not be true for you, and vice-versa.
When such crawlers use a distributed network of machines to crawl, there's no easy way to identify them as such, other than _guess_ that they're robotic in nature due to them coming from "data centre" like IPs (i.e. AWS, Azure, GCP, waht-have-you).
While such requests may well be users using those "data centre" services for, say, a personal VPN... the overall pattern is what gives them away.
Not all users look at a page and then start requesting (maybe from a separate IP, mind you, but still from the same provider yet with the same UA) each URL in that page in succession.
Crawlers who want to stay under the radar are much, much harder to detect as such nowadays.
I'm sure it'll be there, lots of people will be interested in what differences a page shows from different vantage points or to robots, but it's probably less than a percent of all robot traffic.
Though checking the thread above mine, I'm not exactly sure what I was replying to. Didn't it say something about robot traffic that wasn't identifiable as such? I don't see that anymore.

Any plans to make the "continue without disabling" button harder to click in the future?
But I’m curious - do you have any off the cuff stats on what is typical as far as % of users with Adblock across various types of audiences?
Also, on the pricing page there's a "Get Free Analytics" button that you should be able to click. If you have any issues you can let me know: james at getadmiral.
I'm old enough to remember an internet that respected the sacred open ungated plain of knowledge. Publishers lost the privilege to monetize when they insisted on tracking, whether the visitor paid or not.
