I’m assuming that this means that if you select a language, you will only be shown posts of that specified language; therefore, if you choose an uncommon language, you will see very little content (I’m assuming the most common language that is used on Lemmy, currently, is English). The warning, on its own, is rather nebulous, to me.
Most content does not have a language tag. Anything without a language tag is treated as if it has the “undetermined” tag. So if you have not listed “undetermined” amongst your list of languages, then you won’t see most content, because most of it isn’t tagged.

The most used? Yes. The most tagged? No.
You can select multiple languages in the box. The “Undetermined” option is for all posts without a language set. Most people do not set a language on their posts. So unselecting it will hide most posts from you.
This might be desirable if you, say, only speak French and don’t want your feed clogged up with unmarked English-language posts. But it also means that if someone made a post in French but forgot to tag it, you won’t see that post either.
If you’re, say, bilingual English/Spanish, you would probably want Undetermined, English, and Spanish selected in the box.
There are posts older than the language option. Those posts don’t have a language set and ate therefore undetermined. You won’t see those posts if you deselect this option.
Most content here doesn’t have a language set. indeterminite language is just the default.

Just make sure that Unspecified is selected as a language in your settings, in addition to whatever languages you can read. Don’t un-select “unspecified.”
