I am from the US, and was wondering if any kit works on every home toilet.
No. A lot of them work with each other, but not all toilets are the same.
Sort of
For most toilets there’s universal fittings that will work just fine, you may need to adjust them a little bit, but they’re made to be adjusted, and they’ll work just fine with most toilets.
If you have the original factory parts in your toilet, they may not be adjustable, and if you tried to swap them into another toilet they may not fit/work in other brands/models, or they may kind of work, but maybe not quite right.
There are a handful of brands that don’t tend to play well with the universal fit parts, I want to say Kohler is one, and if you go to a hardware store, most likely they’re going to stock the universal parts, then a couple of the most common oddball brands.
There’s also of course some weird toilets that are just totally different- pressure assisted flush, composting or incinerator toilets, etc. that aren’t even working on the same principle as most toilets, but I think the odds are that if you have one of those, you know that already.
Also I haven’t played with any toilets that were manufactured that way, but I did retrofit one of my toilets to be a dual-flush. Those kits seem pretty universal, but probably double-check before trying to put them in an oddball toilet.
Incinerator toilets?
Pretty much exactly what you probably think they are, I think they’re mostly a thing for people living off grid and maybe some RVs

Nope, I’ve seen at least 3 completely different designs, none of those compatible.
Mostly, but as others have said variations exist. Another caveat is that newer/shorter tanks may need to removed to access the nut to change the filler valve.
Nothing new to add, but since crowd sourcing answers is more reliable when you have more of them, I figure it’s worth it.
As everyone before this said, it isn’t a perfect compatibility, so you can’t just grab any random kit and be certain it’ll be 100% right. But, there’s a decent chance it will be, or that you can improvise things enough to get it to work long enough to get the exact right bits.
Biggest problem I’ve run into over the years is flappers not making a good seal, and the pipe not fitting well. The flapper is harder to deal with, but the pipe can usually be made to work with a gasket cut to size, long enough to get a better one at convenience rather than having to run right back out.
While the kits may use standardized plumbing connector, they are not all guaranteed to use the same standard sizes.
I am from the universe.
Our toilets don’t have no ‘kits’.
