The same way that unlimited data plans are capped at a few GBs/month, unlimited SMSes and minutes have limits as well, unlimited bank transaction have a limit of a few ATM transactions per month and so on…
If it's mobile data plan i think you just have not reached that limit yet. Try constant download through out the month and see what happens. I would guess the speed will go down.
At least for my "unlimited" data plan there is contract clause mentioning "reasonable usage".
The only part about "reasonable usage" is that the ISP reserves the right to "temporarily control" your traffic once it exceeds 200 GB/month during a period of congestion "if the congestion is exceptional or temporary".
If they just slapped an overall speed cap on you after 200 GB/month, they'd be breaking their own terms of service.
And that's for a mobile plan. The fixed connection has no "reasonable usage" provisions and just has your generic "reserves the right to shape traffic" stuff.
Unlimited also generally run a lower QCI priority overall so that any other users on the tower will push you out if things are busy. Most people don't even notice this bit. Reddit for nocontract has some posts tracking plans QCI priority levels, and you need a rooted phone to get that info as it isn't published anywhere. I'm happier running a prepaid limited line with QCI8 and being able to get data when the unlimited plans can't.
There's a reason why AT&T Firstnet can do the things it does.
There is also the benefit from AT&T taking those federal firstnet dollars; they sunk a decent amount of money into infrastructure so these priorities / capacity matter less when they have much higher capacity now than they ever have in the past.

It's very hard to obtain a phone plan here that is not some form of unlimited. The cheapest phone plans either have absolutely no Internet, or are capped to like 0.25 or 0.5 Mb/s speeds, meaning that your data cap is just a function of your slow speed.
I don't know where your here is but true, that's another way to do it.
In the US there's competition showing how fast the service is in advertising. Which of course has fine print; "during times of congestion you may experience slower speeds" which is where these priority levels kick in.
If that's on the box. If this can't reasonably be expected and is hidden in an FAQ somewhere, not obvious when purchasing, then a box that says 12 eggs should contain on average 12 eggs. Dunno to what extent variability is allowed (when not purchasing huge amounts); for discrete items like eggs probably not but for gram weights usually it's +/- some amount.
