echoing some other people, this is a scam to exploit you. if youre extremely lucky, youll earn something, but doing a good job is certainly not enough, you still need luck. OF just needs a small percentage of people making money serving as bait to attract a huge bunch of other people to exploit, regardless of merit, and thats the part youll play most likely.
you dont need root for these things. just download the fdroid apk from its website, open the apk (you probably need to allow installing third party apps in the settings, which come disabled by default these days), then search for libretube or newpipe inside fdroid after letting it download its app catalogue (it may seem confusing that fdroid seems empty at first, but you may just need to slide down to update and wait a second for it to download the catalogue).
