It isn't about the stats, absent context. It's about your performance overall, including factors that aren't evaluated in those stats for your perusal, as compared to other players;
1> Of your rank or near to,
2> Of your particular hero,
3> On that particular map, and
4> On that particular side (whether attack or defense).
And that value is further adjusted based on the difference between your team's average SR, and the enemy team's average SR (if you're ranked higher than they are, your wins are less and losses greater, and vice versa).
It may also adjust further based on an internal MMR, pushing you closer to where it "expects" you should be, but that may be accounted for in the performance eval above; this is where we have a lack of clarity.
Track your stats. Get a spreadsheet (there's a bunch already set up you can download for this), track your SR gains and losses, and play enough matches, and you'll see it's fairly consistent. I tracked well over 100 matches last season, and you can easily see in those numbers how my SR gains/losses adjust based on my rank; if my rank dipped, I'd win bigger and lose less, until that trend corrected. It eventually balanced me out around 2550-2600 or so, after starting at 2050; I made that shift in the first 30 matches or so, and the rest I waffled around within a couple hundred point range. The outliers I had in those were games where I knew I'd played exceptionally well (for me), or had shat the bed and did awfully (for instance, playing Zen and getting picked off by enemy snipers regularly). Didn't see a single unusual SR result that shocked me.
Most of the cases where I hear of that, it's people in high or low SRs (low silver or below, high diamond or higher), where there's fewer teams and the potential SR gap between teams is greater, and thus has more effect on SR outcomes. In gold/plat, where I play, that's where most players are, and there's never much of an SR difference (so little I don't bother tracking it).
