Yes I agree, and the replies don't really make it any more clear.
The biggest differentiator of design thinking is really addressing the XY problem. In 95% of cases clients will come to you to design their solution. Ie they already think they have a solution to their problem and now they want it to look good.
Design thinking is basically more like root cause analysis, or the 5 why's.. and an emphasis on taking to end users (the people with the problem) without having a solution.
Once you understand the problem more fundamentally is only when you start cooking up with a solution.
And the result of that process might not even be a traditional design, but perhaps just a tweak to something, like moving your onboarding to later in the ca process..
In practice however.. 95% of designers who say they practice design thinking disregard this, and just want to design wherever the client asks for
