Hope it is improving your knowledge, basically a so called wallet is just 2 numbers that are connected cryptographically. This ensures they are secure. you can use bitaddress.org to generate these numbers offline and thus ensure privacy and security. As long as the computer has never been offline and the bitaddress.org website is run using an ubuntu or linux operating system, there is no possible way your private key can ever have been compromised. Additionally, you have wallets such as Jaxx, or offline wallets such as Trezor or ledgernanoIS offline wallets that do all this for you using a small portable offline device.
