it has always been a mystery to me how such people earn money for their travels

For many travelers, the most relevant earnings are online professions. I have met many web designers, it specialists, and freelancers during my travels. They all said their jobs allow them to travel in small retro campers and have enough money to do it comfortably.
I also work on freelance exchanges and run my own travel blog. It gives me a good income and allows me to plan my activities and schedule. After all, travelers do not have the opportunity to work to a standard schedule and freedom is very important.
