Hello @viveckk ,
Elementor is a commercial product with a large user base, so content creators often focus on it to attract more viewers and potential revenue. The Block Editor (Gutenberg), being a core feature of WordPress, is open-source and free, which may not generate the same level of interest for monetization or tutorials. However, as more people adopt the Block Editor, you’ll likely see an increase in tutorials and content dedicated to it.
From here you can get the best WordPress learning resources, which are not commercial product-based.
