Yes, one serving of olive oil is typically a tablespoon and a tbsp of olive oil is usually around 13g or 14g of fat or about 120 calories.
However, your association between dietary fat and gaining bodyfat isn't entirely accurate. The amount of fat that you gain in your bulk is primarily tied in with the aggressiveness of your surplus, your training, and your biochemistry.
If you think about it as: [maintenance intake] + [extra calories] = surplus, those [extra calories] can be made up essentially however you'd like. Whether you choose to fill those extra calories with fat, protein, or carbohydrates is a matter of preference. Either way, your mixing and matching of macronutrients (after your minimums have been hit) don't have much of a direct impact on how well you partition --- in this particular situation and in relation to fat gain, a calorie is basically a calorie.
Also, utilizing monounsaturated fats (the primary fat found in olive oil) is a very healthy way of rounding out your surplus. It was probably mentioned somewhere in the thread earlier, but testosterone and neural myelination as well as improvements in lipid profiles are typically cited as benefits of having a moderate-high consumption of MUFAs.
