There are a lot of ways in which a website can be powered by a number of different CMS systems. Some CMS systems are great for users who use them WordPress but they're not so great for search engines. When authors create themes for your WordPress they don't necessarily think about Core Web Vitals. So if you are looking to improve these scores first you need to get feedback about why you have the scores you do now and then go on to figure out what you need to do to increase them.
Some of those changes might mean you have to actually split some code between code that you want to load fast and code that you want to defer for later loading. That is an example of an advanced idea but, in the most basic sense you just want your site to load fast. One thing you want to be sure of if you don't know anything about code is make sure you're on a reliable fast host provider because that count tally's into your performance score. Some host providers if they don't respond to a request within 500 milliseconds which is half a second, then that delay is considered bad and you'll get negative scores.
Even quality hosts can sometimes go a little bit above 500 so it's not curtains if you're between 500 and one thousand. I think all of these reports give you a measurement of how fast your server host response time is. You want to make sure that very you're on a high speed host especially when hosting all sorts of assets that can delay and add up quite quite fast.
One thing you can do without knowing any code at all is, make sure you've got a fast host provider.
