What does this statement mean "a conservative force should not be confused with the general law of conservation of energy" ?

Dear student,
the statement " a conservative force should not be confused with the general law of conservation of energy"
means that ,
these two are different from each other. A conservative force is a force by which work done does not depends on the path taken to move an object from an initial position to  some final position. Some examples of such forces are gravitational force, spring force and electrostatic force.
On the other side the general law of conservation of energy  says that total energy of an isolated system remains constant. Energy can be transferred from one place to another , can be transformed in to other kinds of energy but it can neither be created nor be destroyed.

​​​​​​Hence "a conservative force should not be confused with the general law of conservation of energy" as they are very different from each other.
Regards
