Is my project legal? and should I forget about it if its not?

so long story's short, I was building my project I called it "yougle", just like google you search for a word/sentence and then you get where that string you entered appears in youtube videos, I already coded the business logic of yougle, and I already can get where strings appear in videos of some popular youtube channels(pewdiepie, etc..), but the thing is I'm not sure whether this subtitles database I got by scraping youtube is actually legit or not. I read the TOS(https://www.youtube.com/t/terms) of youtube it said that: "You agree not to use or launch any automated system, including without limitation, "robots," "spiders," or "offline readers," that accesses the Service in a manner that sends more request messages to the YouTube servers in a given period of time than a human can reasonably produce in the same period by using a conventional on-line web browser. " violation #1? so basically this phrase is that you can't scrape faster than a human can browse internet, and ofcourse it'll take me years to collect data this way violation #2? in the robots.txt(for those of who you don't know what robots.txt file is, its a file that tells bots which endpoints they should not crawl) file of youtube, it have an endpoint that I'm using to get subtitles out of videos: "Disallow: /timedtext_video" should I forget about my project? what can I do to keep on going with the project while keeping it legit?
