To add to this with my own anecdotal experience: I got into a trade at 18, right outta high school. Had mediocre high school grades, and decent college grades for electrical. Got a job in a place I didn’t wanna work for about a year, but made good connections and got good experience. Used that to get a job in my home town, and literally jumped from job to job, or was able to keep my job through intense layoffs by being a good bullshitter.
Some of the best advice I ever received was “it’s not the grades you make, it’s the hands you shake”
Get into something that might interest you, and network with people. Networking for me from a trades background as a young guy got me a work from home job doing IT in my 30s.
Best of luck mate, you’ll figure it out. Time is on your side, just don’t be idle for too long if you can help it. Older you will thank you.
I switched from Windows to Bazzite on my main rig 2 weeks ago. Likely won’t go back to Windows for gaming as I’ve had pretty much no issues with Bazzite.
I did also get a Steam deck recently, so anecdotally, both above answers are right.
