can this make sense to you?

Not really without further context.

Of course, however your question should read.. Does this sentence make sense to you?
100/2 = 50
If one is right, the other is wrong. If one wins, the other loses. A contradiction is opposites. Black, white, up, down, in, out. For people, what is nirvana for one person, is often poison to another.

The simplest interpretation involves two opposing forces in balance. Any gain on one side results in a loss for the other side.

thank you

The writer is using the word "contradict" incorrectly in this sentence.

It sounds like a description of a zero sum game.

Exactly, max. That's what stopped me in my tracks, the use of the word 'contradict.' The rest of the sentence makes sense. 'Negate' each other might have worked here.
