If your main competitor is a Series B startup in an emerging field, how do you beat out?

So I am working on a project, and after prototyping I later learned that a Series B, is the main and probably only one or two competitors in this space? How do I not deal with imposter syndrome and flip this as a good sign. These guys will probably continue to get funding as they partnered with JP and small businesses. Like these guys have both the hardware and software down. And I dont have any funds for those On one end its like, well if these guys are getting funding then I for sure can. If these guys are Series B then there is for sure a problem in this space. There are multiple companies that do the same thing, think Uber, Lyft. UberEats Doordash Grubhub Postmates On the other hand its like these guys are a lot more older/established than I am, they're 47, 43 im 20 (first time founder? (i dont know if i can call myself a founder lol/indie hacker). However people like Zuckerberg and Co beat out MySpace,Friendster, LiveJournal etc at 20. For people in the same position as me, what advice would you give me. Use their own product?
