(eli5) Why do some of the world’s largest Oil producers (Exxon, Shell, BP) have such a low stock price compared to Big Tech (Amazon, Google, Apple) despite having similar or better revenue?

Pretty much just this question. Why does Shell have a low stock price compared to Apple despite having more revenue?

Stock price isn't an indication of a company's worth. Market cap is. Market cap is Outstanding Shares multiplied by stock price.

A company that has 100 outstanding shares valued at $1 each, has a market cap of $100.

A company who has a stock price of $100 per share, but only has 1 share outstanding has a market cap of $100.

In this scenario, both companies are valued the same, despite the disparity in stock price.
