Check the result is equal to set(secretword), I think you mean.

set(secretword).issubset(set(lettersguessed))

might be slightly more efficient, since it would not need to build and
return an intersection set.

One might also just do:

all(letter in lettersguessed for letter in secretword)

Which will be efficient if lettersguessed is already a set.
