Yes. Lots and lots of examples of this. And not just wix or wordpress. Pretty much all site builders will struggle with SEO when measured against a modern CMS where you have full control.
But even then, a poorly configured CMS (like wordpress) with a ton of plugins and bloated theme will do less well than a slick, fast and properly structured site.
Google scores your site performance at 58/100. With wix you won't get much better. A well built wordpress site can easily score 99/100. Note that performance is just one of many ranking signals so treat this as just an indicator.
The more important ranking signals are content, navigation, structure, trustmarks and calls to action. Then there are a whole load of technical considerations that you can't fix with wix.
