Just because you claim it's betting doesn't mean you're correct, at all. Here you are now trying to claim that everything is betting. No, curation is not betting, no, not everything is betting and no, just because some make more it certainly does not make it betting.

Here's the definition of betting:

bet (bĕt)
n.

1. An agreement usually between two parties that the one who has made an incorrect prediction about an uncertain outcome will forfeit something stipulated to the other; a wager.
2. An amount or object risked in a wager; a stake.
3. One on which a stake is or can be placed.

It's not about looking for the bright side, it's a matter of not twisting words to mean anything and everything, which renders the word meaningless. It's the same for curation being twisted to mean that it's not curation if you're rewarded for it, and you're twisting betting to mean anything that comes with any sort of risks or simply anything that isn't "fair", or "equal" is betting, which is not what betting is at all, and certainly not what curation is.
