In short. The Rich Results Test preview is a conditional example, and Google's live Search presentation can differ.
Definition: No. A Rich Results Test preview is an example for some structured data driven result types and layouts. Google says that the page shown in the preview can differ from the result shown for a search request.
Key facts
- The Rich Results Test can preview how some result types might appear in Google Search or Google Assistant, according to Google's Rich Results Test help.
- When a page is eligible for multiple Search result layouts, the tool can show selectors for desktop and mobile layouts.
- The tool lets you choose a detected result type and a desktop or mobile version, then rerun the test after changing the code.
- Google's structured data gallery says actual Search appearance might differ and that most features can be previewed with the Rich Results Test.
- Google's structured data overview describes the test as a validation tool and, in some cases, a feature preview.
What does the preview represent?
The preview represents one supported rendering for a detected result type. The test first reports which rich result types it found, together with structured data errors or suggestions. For a page URL, Google's help requires page resources to be accessible to an anonymous user. The test also accepts an arbitrary code snippet, so you can change markup and rerun the test before publishing.
The test supports JSON-LD, RDFa, and Microdata. It can use a smartphone or desktop user agent, with smartphone as the default. These controls affect the test input and the view offered by the tool. They do not select the search request that will later determine which result presentation appears.

Why can the displayed layouts differ?
Google's help describes selectors for different layouts when a page is eligible for more than one Search result layout, including desktop and mobile searches. The tool can also show a selected result type and let you switch between device versions. A change in the tested code can produce new layouts inside the tool.
The structured data gallery separates feature types and their examples. It describes a breadcrumb as navigation showing a page's position in the site hierarchy. It describes a carousel as a sequential list or gallery from one site, and its examples include several feature families. These are different result presentations, so a valid item can have more than one documented visual treatment.
Google's help states that the page can appear differently from the preview and that the displayed views might not be applied to the page result. It attributes the search presentation to the search request, including the user's search history and location, plus other variables. The gallery likewise says that actual Search appearance might differ.
What should you check on a website?
Use the test to inspect detected types, errors, suggestions, and the rendered source used by the explorer. Google's structured data overview says the tool is for validating structured data and, in some cases, previewing a feature in Google Search. The same overview says that all required properties must be present for an object to be eligible for enhanced display in Google Search.
After deployment, Google points to Rich result status reports for monitoring validity. A preview is therefore a development check for supported layouts. Search Console reporting and the search result itself are separate observations from the tool's rendered example.

FAQ
Does a valid test mean the same result will appear in Search?
No. The test reports detected structured data and issues, while Google's help says that the preview and the page result can differ.
Should you inspect both mobile and desktop views?
Yes, when both search surfaces matter for your page. The help page documents selectors for desktop and mobile layouts and lets you choose a device version.
Why is there no preview for a detected item?
Google documents previews for some rich result types. The structured data gallery says that most features can be previewed, so a detected item can remain a validation result without a corresponding preview layout.
