FMJ doesn't expand.. well it's not designed to anyway, and usually doesn't under most circumstances.
JHP's are designed to expand.. why is this important?
because 9mm aprox .356 inches might end up being .650 if it's designed to expand (JHP).. nearly twice it's starting size.
bigger size = more damage. Additionally the energy used to expand means it is less likely to over penetrate (that is pass thru target with significant velocity)
FMJ will penetrate deep but leaves a smaller wound track and will usually exit the target with significant velocity (potential to injure someone else)
FMJ is cheaper to make, used for the range, JHP are better for defense and cost more to make since they're more complicated to make.

This type of ammo is the most common type for centerfire pistols and rifles and carries quite a bit of force. However due to the dense and "balled" nature that the lead is configured in, FMJ ammo has a tendency to "over penetrate" targets. In other words, they can go right through people.
While this may seem ideal, in actuality you want as much of the force from the round to be transferred to the target as possible instead of flying right through.
To solve this issue, manufacturers started creating specialty rounds called "Jacketed Hollow Points", or more commonly referred to as simply "hollow points", and began marketing them specifically for personal defense.
In these rounds, the actual projectile carries a more complex shape/molding of lead and typically is only partially jacketed with copper or aluminum. When fired at ballistics gel or other fleshy substance, JHPs are designed to expand and spread out as much as possible so as to create a more devastating wound and ideally transfer as much force to the target as possible.
JHPs, to my knowledge, have been around for 30+ years and have seen multiple generations of tech as manufacturers figured out how to make the rounds expand (and stay contiguous) more and more.
The Federal HST line represents the latest in personal defense round technology and has seen very positive results both in testing and law enforcement usage nationwide.
Due to the extra technology/research that went into the round, as well as the presumably more expensive materials and manufacturing processes, JHPs cost more than your traditional FMJ ammo. However since most folks aren't using JHPs for target practice (except to verify that their selected brand doesn't disagree with their defense weapon) the cost isn't viewed as particularly deterring.
TL;DR: Use FMJ for range practice, use JHP for personal defense.

I am new and do not know much, but is there any noticeable difference if I shoot you with the bullets I bought from the range and the bullet I bought on here?

Shortcut to the answer for the common question of "What is the best self defense ammo?".....

JHP = jacketed hollow point.. which is the TYPE of bullet it is.
.. Metal jacketed lead with a hollow cavity that is designed to expand.
another way of putting it is HST = Snickers and JHP = Candy bar.
