I think the interactive demo is excellent.
I considered that the distributions are randomly generated with each click, and tried multiple clicks. I found that you can quite easily get both yes and no for significant difference with some ‘borderline’ parameters. But then I found that occasionally even an identical mean and std (1), with 200 samples throws out a Yes amongst the vast majority of Nos. It happens with the std at 5 too. And with the mean as high as it will go.
Why is that? I guess it is the sample size being still fairly small.
