Knock down any peaks with a wall scraper blade or aggressive sanding, then skim coat till smooth. Sanding is messy, wear a mask, cover and tape places you dont want dust and test paint for lead first.
Your walls seem fairly flat, so you might be able to forgo the sanding and mess it creates. I would just give it a once over if so, just so a thick paint bump doesn't add 3 extra coats to your skim job
Either way step one is a TVP wash, cleans oils off, makes surface more porous and ready to paint/mud
Buy mud, mix till yogurt like, so a little more runny than the premixed comes. Add water slowly, cannot remove water. A mixing paddle and drill and 5 gallon bucket works fine
Thick roller on a pole is dipped in and applied to wall
Smooth with a wide trowel. I like the 24" rubber edged ones
Let dry, scrape peaks off, repeat till wall surface is all mud, sand smooth, primer, paint
check wall by shining a bright light against the surface, looking for imperfections in shadow cast
Its laborious and tedious, but not hard. Easier and cheaper than replacing with drywall, but not faster
You'll be proficient after a google search and you finish your first wall. Good luck!

You can do both, probably should.
