The reviewer’s labels for ranges of correlations are arbitrary, but reviewers can be arbitrary. If you did label your correlations as "strong" or "moderate" etc. I would just remove those labels.

As far as p tests for correlations go, these test whether or not a correlation is significantly different from zero. So, you can just say something like "All of the correlations were significantly different from zero" and avoid reporting any specific p values.

The correlation was reported with two statistical parameters: the first being r (correlation coefficient) and the second being p value. r simply reports the amount of relation between two variables. As the reviewer mentioned, a correlation coefficient between .90 and 1.00 indicates a very high correlation; .70 to .90 indicates a high correlation; .50 to .70 represents a moderate correlation; .30 to .50 is considered a low correlation; and correlations from .00 to .30 are regarded as negligible. However, since you are sampling, the p value indicates if the correlation you observed is significant or if it occurred by chance.

Example: If r=0.8 and p value = 0.7, it means there is a high correlation between two variables, but it is not statistically significant, and this correlation occurred by chance.
