Variance is standard deviation squared, but in the context of this conversation they are mostly interchangeable.

Win-rate has very little to do with variance. If you are crushing and 90% of your sessions are between $0 and+$1000, your variance would be exactly the same as someone with 90% of their sessions between -$500 and $500. The first player with a much higher win-rate will rarely have downswings while the second player will be all over the place around $0, which is what I think most people mean when they say the first player experiences less variance, but they are using the term incorrectly.
Deeper stacked play very obviously increases variance due to larger pots being possible, up to a point where large stacks just stop being in play I guess.
