Heya, thanks for the question.
I don't think a master's thesis would be considered a reliable source as is. It's more an introduction to academic research where students demonstrate that they are able to conduct research and be honest and critical of their work. The university is checking that I satisfy the requirements for my degree, which includes my committee evaluating the quality of my thesis. For my results to be considered in wider academic circles I'll have to be published. I might be able to publish articles from the thesis, but that will depend on my results and whether my professors and any journal I submit to think my research is worthwhile. Not all articles have equal quality, but there is a peer review process that is meant to check for quality.
My data, specifically, is currently drawing more from a specific gaming community and I will be mentioning that several times in my thesis to give context for my results. I was hoping for more data so that didn't happen, but it's part of the process and I'll be mentioning it in my discussion. But I've certainly learned a lot, including not repeating the mistake I made here. 😅
(And, to your previous post, my survey is unfortunately a bit long. I tried my best but I got a little excited. It doesn't require a social media login though, that doesn't sound like something my IRB would even allow. It's hard to imagine those that do are academic since anonymity would be a big issue there. By the standards of my department, anyway.)
