I think we can set guess = Character.toLowerCase(guess) in the charGuess method. This can solve the problem in 1 line.

Don't know what the difference is between my way and the video's way

This is most probably true, but it would be more logical to first check whether the guess is a letter in the first case. If guess = '@', for example, Character.toLowerCase(guess) will result in $1 => '@'. As you see, this was a useless call of the function, though. It would not have been so strange if, calling this function on a non-letter Character like '@', it would give an error. (Luckily?) it doesn't!
