Stealing bitcoin is not that hard if the person is irresponsible saving their keys. But hacking is almost impossible, if you are responsible not to download or go to phishing sites then you are 100% safe. If the hacker already know about your keys and your email address they can steal it in an instant. But if you will try to decode their passwords since most of our wallets have multiple keys it will take them forever. Bitcoin is safe just don't let your keys and email exposed to any phishing sites or any computer that you don't own. Use it in your personal computer or phone and you are absolutely safe.

So is it JUST down to possibility? Everyday that possibility gets less as more people join and more keys are made, I have bigger chance of Hitting a wallet with a random key?

Yes. The only security is the extremely unlikely possibility that you can guess a private key. And yes, that possibility gets slightly lower as more and more Bitcoin addresses are used (since you only have to guess one of them instead of one particular key). But there are about 10^77 possible private keys. For comparison there is something like 10^78 to 10^82 atoms in the visible universe. The security comes from the very large size of the number.

But to be clear, if someone can guess a private key, they can access the Bitcoin associated with the Bitcoin address generated from that private key. They don't need anything else.
