This video is about physics vs math and how to know which major is right for you. You may have enjoyed them both in high school so of course you may want to major in one in college.
The good news is that if you major in physics then you will take a lot of math classes to the point where you COULD almost have a minor. But as a physics major you will not take a lot of high level math courses that are very important especially for pure math students. Pure math students and physics students actually have very little in common. Physics majors care more about math that applies directly to physics concepts, while a pure math student cares about solving problems within mathematics alone.
Then note as a math student you will likely take very few or no physics classes throughout college (unless you get a minor). You will learn math concepts that can be applied to physics concepts (such as differential equations to solve for the motion of a mass on a spring), but you don't directly learn the physics behind them.
Both math and physics have a wide range of job opportunities and often it doesn't necessarily matter which major you go into. It's more important to know what kind of job you'd like to go into, and pick a major that sets you up well (but often there isn't a right answer).
Also note that with a major in applied math, you should consider getting a minor in some other discipline.
