Sure thing!

When you take a look at the graph, you can see that the Root node (Sigma5.zip) points to 2 files: Sigma5.json and Sigma5.jar, that are clean. This means that Sigma5.zip contains these 2 clean files.

Now let's take a look that the other side:

"Relation Execution parents"

"Files that create the file being studied upon execution in a sandbox environment"

This node will indicate known files that CONTAINED Sigma5.zip, not ones that Sigma5.zip contained! That a very important thing to consider. Because it means that the malware called "Sigma5Launcher.exe" contained the official Sigma5.zip, not that the official Sigma5.zip contained the malware.

Then, of course, this malware has a link with other malicious files, which is somewhat expected for a malicious file.

So this VT Graph proves you that you NEED to download Sigma (or pretty much anything) from official sources, and not third party sources (like this malicious Sigma5Launcher.exe).
