I'm trying to test my react application using the Audits tool of google chrome. I took a look of the performance of another sites to discover the performance. I tried facebook website; I check Desktop device, and all the checkbox audits then I choose Simulated fast 3G, 4x CPU Slowdown and I check the clear Storage. I run the test in a private navigator then I got this result:

I tried the test many times and every time is under 50%. Is it normal that the performance of a great website under 50% or these values are relatives?

I've analyzed many such websites. Yes, even popular websites like Google, YT, FB doesn't score well. The reason is they don't care about it
For example, Facebook doesn't need any improvement in SEO. They're already in the first position, nothing more to optimize!
In the case of performance, and other variables, it's possible to achieve 100%. But you'll need to remove some functionalities
For example, in my case (in my website), I can remove Hotjar and some 3rd party scripts to achieve 100%. But for me, those are more important than what Google says
