What are Cryptocurrency Wallets?

Reading through Wikipedia regarding Coinbase seems it is called a Cryptocurrency Wallet.

According to my Internet search: (I liked Crypto Currency Facts)

"What is a Cryptocurrency Wallet"? Sit back and let's go through this slowly.

• It should be a secured location also known as a wallet
• Cryptocurrency is NOT stored in the wallet
• A wallet like Coinbase I signed up with also known as a cryptocurrency wallet is where a private key is stored.  (Its suppose to be a secure digital code known only to the wallet's creator.  Share this code with NO ONE!)
• This private key will show ownership to a digital code connected to a denomination of virtual money also known as digital money also known as cryptocurrency.
• These wallets (cryptocurrency wallets) like Coinbase can store private and PUBLIC keys!
• The purpose of these wallets are so ones can store, send, and receive digital/virtual/cryptocurrency monies through "Using" the Internet.  
• A wallet is ones ones personal ledger of transactions showing/tracking ones transactions only in virtual space on the Internet using a servicing company like Coinbase.

Thinking this through its learning new words from the hands on world I use now.

• Instead of going to my bank I will have a virtual bank through the Internet, "Online".
• Instead of a bank account and routing numbers I will have keys and a digital code.  
• The digital code is where I will find my money.
• To get to my money I will need to have a key to prove I own that digital code.

Someone help me out here to verify I'm on track.
