The auxiliary verb "can" refers to ability to do something, which may express a degree of ability. For example, a crossbow bolt case "can hold up to twenty crossbow bolts." In this sentence, 20 is the degree of ability the crossbow bolt case has - it can hold anywhere from no bolts up to 20 bolts.

The text often uses the language "up to" to help clarify, but this is not strictly necessary, and is missing in a few cases, notably in race longevity, the movement and jumping rules, and the sculpt spell ability.

"an elf... can live to be 750 years old"

Every character and monster has a speed, which is the distance in feet that the character or monster can walk in 1 round.

"Your strength determines how far you can jump."

When you cast an evocation spell that affects other creatures that you can see, you can choose a number of them equal to 1 + the spell’s level

It is natural in each case to read each degree of ability as a maximum ability, not an obligation to live to exactly 750 years, move exactly a distance equal to your speed, or preserve an exact number of creatures. When the text indicates something that you are obliged to do, it uses the auxiliary verb "must".
