Design Thinking is a type of work where it's not just for you. You may need to solve other peoples' problems or problems you think are important. You can create things that slightly important or things that will change the world. All in all, you will make useful thigns in the real woord. You can still use digital tools, though.

When doing design thinking you need to change your perspective and fit people's needs. You need to think of the consumers. You need to also collaborate and be a team member. Not every answer is correct. You need explore other possibilities. You need to be ready for failure. Make prototpyes and multiple versions. Design thinking is very hands on. Like I said, you need to try and try and you will fail at least once.
