Cholesterol
". . . olive oil typically contains 0.5–2 mg cholesterol per kg and sesame oil about 1 mg cholesterol per kg."
Cholesterol is used by the liver to make bile acid, which is stored in the gallbladder until needed. from whence excreted as bile salts to aid the digestion of triglycerides (edible oils). Most bile salts, up to 95%, are recovered in the ileum (lower small intestine).
Given the body's ability to synthesise cholesterol and that most is 'recovered' there is no need to consume cholesterol in the diet.
All animal cells manufacture cholesterol with relative production rates varying by cell type and organ function. About 20–25% of total daily cholesterol production occurs in the liver; other sites of higher synthesis rates include the intestines, adrenal glands, and reproductive organs.

The body produces about 1000mg per day (1gramme) to maintain around 35grammes in a 68Kg body.
The daily cholesterol intake from food in the US is some 300mg, whereas less than 200mg is recommended.
Behrman and Gopalan (2005) suggest the following as an accurate account of the real sterol content of plants:
More than 250 steroids have been described in plants. Of these, perhaps sitosterol, which differs from cholesterol by an ethyl substituent at position 24, is the most common. But plants also contain cholesterol both free and esterified. Cholesterol occurs as a component of plant membranes and as part of the surface lipids of leaves where it is sometimes the major sterol. The quantity of cholesterol is generally small when expressed a percent of total lipid. While cholesterol averages perhaps 50 mg/kg total lipid in plants, ....
... For example olive oil typically contains 0.5–2 mg cholesterol per kg and sesame oil about 1 mg cholesterol per kg.
Give the above figures a person would only obtain 50mg of cholesterol from 50g of sesame or olive oil. Given that sesame seed is 50% ol then you would need 100g of seed to get 50mg of cholesterol, a small amount. See https://www.vegfamily.com/dietician/cholesterol.htm
Other than oil rich seeds cholesterol levels are rather insignificant in other plant foods.
