Technically these are all still Latin leters, just that they’re written in a weird way that evolved from middle-aged Gothic handwriting as opposed to Latin directly which was the case with English cursive. This style of writing, along with the print-oriented 𝔣𝔯𝔞𝔨𝔱𝔲𝔯, was abandoned for the Latin equivalent by the Nazis for logistical reasons in 1941.

I actually learned Sütterlin in school, not as the standard but as an alternative cursive.
I already hated cursive, having to learn another and on top of it outdated writing system was the first of many ways schools wasted time I have experienced.
Yeah, I hate how they insisted you do it their way with surgical precision when your own way is legible too.
We had a course in elementary school called “fine writing” or “beautiful writing”. Mandatory, of course. I was completely fine with “legible”.
