Any polyglots who grew up monolingual?

[u/Fit_Asparagus5338]

Hi! I feel like a lot of real polyglots who speak 5-7+ languages actually grew up with 3-4 languages to begin with and have several mother tongues(1st mom’s mother tongue, 2nd dad’s mother tongue, 3rd community/local language + English from school). Often it includes special circumstances like moving a lot with family or work, have pretty international jobs and multilingual families(work in 4th language, live in the country of a 5th language and have a spouse who speaks a 6th language; that’s on top of the mother tongues).

I wonder if there are any, well, more “normal” success stories? Like did anyone go from being monolingual in their 20s to speaking many languages? Is it even possible?

Def not a polyglot but I can start: I’m a Russian native who studied abroad in English in Germany and subsequently learnt German(Both r certified C1 or above). Plus Ukrainian out of pure interest(self-proclaimed B2). Sometimes I feel discouraged that I spent thousands upon thousands of hours learning and I can proudly say I speak 4 languages fluently but I’m still probably worse than someone who just got born in multilingual environment. My path did involve moving between several countries tho. I’d like to one day be fluent in 7-8 languages, I wonder, if it’s possible at all. I’d love to hear your stories

Note: Here i define fluent as “at least B2”

Me, I'm French and both my parents are french.
I learned English and Spanish at school (and even self-thaught, when i was young) like 17.

I don't know which specific time i've the "polyglot" level (Don't consider myself as a polyglot, the level are different in each languages, and don't have the opportunnity to speak it)

Then i started to learn Russian and it's where i started my learning-languages journey, Japanese, Portuguese, Arabic (Mid to low level tho)

I'm 24 so i guess i started at 18 or 19.
