There's no better way to understand the principles of load bearing and non load bearing walls than to have a look at them in action. Try to find a timber or steel framed building under construction, with the wall and roof framing up, but before the bricklayers have got too far on the walls.

It's likely that the building will have a trussed roof, because that's the most economical way to build these days. Have a close look at the bottom chord of the truss as it passes over the non load bearing internal wall frames. You'll see that the bottom chord doesn't rest on these walls at all - it's only bearing point is at each end.

Now look for internal load bearing points in the building, that is, points where a wall is supporting part of the roof or the second storey floor above. What is holding up the load? Is it a wall frame or a beam? Is there a column involved?
