comment Intuitive meaning of the concept “computable”
Yes, that is right, there exists an algorithm but we don't know which one. There are even situations where we can't possibly know, for example if $K(x)$ is the Kolmogorov complexity, there exists a $n_0$ such that for all $n \gt n_0$, no statement of the form $K(x) \gt n$ is provable. Yet there is an algorithm that outputs $1$ if $K(x) \gt n_0 + 1000000$ and outputs $0$ otherwise, because there are only a finite number of strings with Kolmogorov complexity less than any constant.
