And that's actually a pretty recent development. Less than a decade ago, I remember getting marked down in English class for using "they" as a genderless singular pronoun, as my elderly teacher grew up only ever using "they" to refer to a group.

This use of singular they had emerged by the 14th century, about a century after the plural they.[4][5][2] It has been commonly employed in everyday English ever since and has gained currency in official contexts. Singular they has been criticised since the mid-18th century by prescriptive commentators who consider it an error.[6] Its continued use in modern standard English has become more common and formally accepted with the move toward gender-neutral language.[7][8] Though some early-21st-century style guides described it as colloquial and less appropriate in formal writing,[9][10] by 2020, most style guides accepted the singular they as a personal pronoun.[11][12][13][14]

Your teacher was just one of those purists and it was never something with strong consensus for being wrong.

Shakespear used they as a singular iirc

And Chaucer split infinitives, but I was always told it was "wrong" in gradeschool. That's the problem with pedantry: language is a fascinatingly complex and beautiful set of patterns. Boiling it down to rules is at best a handy style guide for formal writing, but at worst it gets weaponed as a way to discriminate against people who use lower prestige dialects.

That's true, and there is evidence of "they" being used as a singular as far back as over 700 years ago, but only within the last few decades has it been formally accepted by style guides, like the APA or the Chicago Manual.
