Why doesn’t Google guarantee the display of rich results?

What is the context behind this statement?

Google uses complex algorithms to determine if a rich result should be displayed or not. The lack of guarantee is related to how Google evaluates the relevance and quality of the marked content.

How does this affect my SEO strategy?

The random display of rich results can influence the click-through rate and, by extension, organic traffic. SEOs need to adjust their strategies by integrating elements that enhance the overall quality of the page.

• Relevance takes priority over technical markup.
• Rich results are subject to unpredictable algorithmic fluctuations.
• There are no notifications in Search Console for changes to rich results.

Does this statement align with observed practices?

What nuances should be added?
