From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Many people use laptops and use other wifi networks or tether to their phone, both can expose you because of unknown firewall states or IPv6 being used.
Yes, I am one of those people, literally all the time. This is the point of laptops.
And I use default Ubuntu Desktop config, kept up to date of course.
If that makes me and OP sitting targets, then maybe we should address this concern to the people who make distros rather than to a random anxious newbie.
Your phone tether will NAT you and not route any incoming packets that aren't part of a connection initiated by your host. Firewwll does nothing and anyway you wouldn't even have any open port inside the LAN unless you run services that open ports.
