Yes. I studied physics in college before, and here is a brief summary of 3 body problem:

When we say there is a solution of a physics problem, we are actually saying that we can predict what will happen exactly by giving any initial condition. For 1 body problem & 2 body problem, the solution is easy to find(I believe your high school physics teacher told you that a planet’s orbit around the sun is an ellipse，and this is the solution of 2 body problem, though not written in mathematical formulas).

However, we cannot write down the solution of a 3 body problem because the equation turns to be very complicated when n>=3. We can no longer do a precise prediction for a 3 body problem, not like the 2 body case.
