alt Hacker NewsIf someone was wondering if this is statistically significant after reading the first line in the method and seeing 41 interviews, then the answer is probably yes, as the final results are based on a study with 336 full-time university students.

The final results were from a survey, not a study where they trialed Super Mario games on students and followed their progress.
Also did you notice that the numbers in your quote don’t even agree? In parentheses the numbers are out of 41, not 336.
This is not a serious paper.
It's "statistically significant", but it doesn't really say what the title says and they draw a lot of causal conclusions that don't really follow the data IMO. The main result is really that happiness and burnout risk were negatively correlated (what a surprise, people burning out aren't happy?), although the caveat is that's only shown in Mario-playing college students.
