We appreciate you are interested in stats. Though, I will note that a failure to reject a null hypothesis at a set alpha is not evidence towards the null being true. As noted it could be a sample size issue. To formally test a null value, a threshold is usually stated for a margin of similarity (e.g., equality test).
I will also second that a pvalue associated with a correlation does not provide information on the correlation value, but is a frequentist statement about if you repeated the study.

Also, to the OP - constructing a scatterplot may be beneficial as well!
