For the purposes of establishing stationarity in a time series, does an Augmented Dickey Fuller test with a super low p-value prove that my time series has a constant (enough) variance over time?

pic related is my time series. It looks stationary to me, but I'd like to establish that more rigorously than just eyeballing it.
adf test p_value is 0.00000084. 5% level of significance.
