Not a great video because it fails to mention the fees and other challenges that the fund has in investing in oil. Oil prices are not the same for all dates. Contango occurs when the future price of oil is greater than the current price. Thus, sometimes USO is buying oil in the future and it loses some percentage over time.
What Contango Means For Oil ETFs In other words, in real life, USO and other ETF's have costs that may hurt them from mirroring the price of crude. I would not let this discourage you necessarily but if you are investing, it is good to know all the facts.
There are also other ways to invest in oil. Royalty trusts, are just one of those. Generally, an oil royalty trust owns a specific field of oil. When they sell that oil, the holders get dividends if the oil is above a certain price. As oil goes up the trust earns more money. These trusts though decline over time as eventually the field runs out of oil, usually it takes years and they can give you estimates on this. There are both publicly traded trusts and private ones.

Of course you can also invest in oil companies, drillers, oil field equipment, retail gas sales, refining etc.
I do not recommend or discourage oil investments. Pricing is all about supply and demand. Demand is terrible right now and supply is plentiful because the Saudi's and Russians are not on the same page on limiting output. If the Saudis are smart they will wait until many of the USA companies go bankrupt. Whiting Petroleum was the first since COV-19 to do that.
