In the universe? Doubtful.Even the visible universe (aka whats been close enough to us for its light to be able to reach us in the time that star existed) there are many, many suns, planets and what not. Money -aka didgets on a computer - is liquid power. But in a civilisation a mere 50 years of good scientific work ahead of us, even the poorest would have more power than this guy. Feed the world? No problem, just send the nanobots to collect nutrients from wherever and 3D print a few protein sequencisers or whatever... Throwing money at it might be sufficient or it might not be. At some population it definatly wouldnt be - sure, you might have enough money to pay for 50% more than is globaly consumed of ressource X. But if we cant produce ressource X at that ammount, youll end up with the same amount, only that you have raised the price by 50%. Now, im not saying his money wouldnt be helpful at all. I am all for taxation, universal healthcare or an unconditional base income. But we still shouldnt overlook that if you buy something, it affects the economy which in turn effects what you can buy.
