Variance influences a player’s session results by creating fluctuations in short-term outcomes, regardless of skill level. It leads to sessions where luck, rather than strategy, plays a dominant role, which can result in unexpected wins or losses. Over time, high variance can mask a player’s true performance, making it challenging to determine whether results are due to skill or chance. This randomness is inherent in many games, ensuring that no two sessions are alike and adding unpredictability to each outcome, despite underlying probabilities and strategies.
 
Variance is indeed a key factor that greatly impacts a player's session results in games like blackjack. This statistical concept refers to the degree of dispersion or spread of possible outcomes around the expected value. In the short term, variance can significantly influence a player's session results, often overshadowing the long-term effects of skill and strategy.

During a single blackjack session, variance can lead to swings in luck that may result in unexpected wins or losses, regardless of a player's skill level. This means that even a highly skilled player can experience losing sessions due to the random nature of the game. Conversely, a less experienced player could have a winning session purely based on favorable variance.

Over the long run, variance can make it challenging to accurately assess a player's true performance. High variance can mask the impact of skill, as short-term luck streaks or slumps can distort the overall results. This is why it is crucial for players to focus on making mathematically sound decisions based on strategy, rather than getting overly influenced by short-term outcomes.

Despite the unpredictability introduced by variance, understanding and managing it is essential for long-term success in blackjack. By acknowledging the role of variance in shaping session results and maintaining a disciplined approach to the game, players can navigate through the ups and downs and strive for consistent performance over time.
