Can options stocks make money after the company goes public?

At present, in China, after a company goes public, its share price usually rises, and the value of natural option shares will also increase.

If the market price of the company's stock exceeds the subscription price on the option when the option expires, employees can exercise their rights to buy the stock at the subscription price and sell the stock at a higher market price, thus making a profit.

If you have any details, you can also ask me, hoping to adopt them.
