"averse", not "adverse"...

As for poker...too much randomness. Better understand how to bankroll, not just how to play poker well. If not you will lose your shirt, repeatedly. It's actually just as bad a way to make a living as chess...there's just a larger pool overall because the barrier to entry is lower to play poker "well".
I still think it's reasonable to say that risking money already in your rightful possession on what might boil down to the turn of a card (and often does) is not sensible. I don't see that affordability comes into it. BTW, what is +EV? My education is clearly sadly lacking.
Positive expected value i.e. if you repeat the scenario infinite times you will be a winner overall. A factor of the probability/returns.
You could say the same to anyone starting a business about risking money in your possession. Any business is influenced by unpredictable circumstances. Clearly you're risk adverse, which is fine too.
Poker winning is about long term results. Thus it doesn't come down to cards except in the short run.
People starting businesses and risking investment do so normally having carefully researched their prospective markets and decided that they can be confident of success in the prevailing conditions. In a card game played for money, you can only be confident of gain if you know you are up against clearly inferior opposition and even then, the cards might well thwart you.
