According to the most popular website about cryptocurrencies - the number of available currencies is well above 1000! If you are thinking that's too much to learn, don't worry, not many experts know what comes after the first 100, so you'll be fine learning about the first 10-20. You can check the list of all cryptos, their price and the market capitalisation using this link: https://coinmarketcap.com/all/views/all/

You also shouldn't worry about words like "market capitalisation" (or market cap for short). This term simply means taking the price of the coin and multiplying it by the number of coins available.
