Weather the hacker was poor or not does not matter. What matter is you got hacked in your wallet where the only one that should have access to it is you and you alone specially that the only way to access it is by private key and that only means that you are not careful enough to keep this important data from being stolen. The only lesson that can be taken from here is that you need to be careful on where you access your crypto accounts and wallets and providing personal data from spreadsheets. Learning basic internet protection also helps a lot.
