TypeScript would have to become more popular than JavaScript for your last part to become true. And it's nowhere near of getting there (outside of SV/hip development world).
I don't think that's a fair metric. Many people using TS (myself included) will typically use "JavaScript" in search queries because the answer is usually the same. The only time I search for "typescript" is if I have a problem with the type checking, which isn't very often.
That said, I think you're right that JS is still quite popular.
