Can a Whonix connection be spied on?

When Whonix is connected to Tor (using a WiFi router), is it possible for someone nearby to spy on the Whonix connection? I’m wondering if Whonix has features that block potential spying.

As far as I can tell, the connection sequence is this: [Tor within Whonix] >>> [Whonix] >>> [WiFi router] >>> [Internet]. Is it possible for that sequence to be compromised? (i.e. spied on)

It’s asking like “how secure is it” / “is it secure”?
Whonix was founded 7 years ago. Therefore tons of things were written on this subject. You can find a lot information on this subject on as from many third party resources. Therefore won’t rehash the question here since it’s a too unspecific question.

What I’m wondering is – does Whonix act like a tunnel? Is it similar to a VPN?

When data is being transmitted from Whonix to the Internet, can that data be monitored by someone near the WiFi router? In other words, is it possible for people to eavesdrop on a Whonix connection, and see what websites the Whonix user is visiting?

Also, will adding a VPN on the host computer improve anonymity?

Whonix uses Tor. Not VPN.
