Tutorials and Guides
This data pack, the target of the random is @s which mean you can target your own entity. If you just type command /function random:next/xfor example:
/function random:next/10When you set scoreboard random as sidebar, you will see a random number generated randomly.
However, if you put the previous command in command block, it definitely not work because the command block has no target as @s. What you need to do is put execute command to dedicate the target so you need to type (in command block)
execute as <target> run function random:next/xfor example:
execute as @p run function random:next/69The random number will create in range 1 to 69 for the nearest play(@p).

To set random in another scoreboard variable, you just need to use equal operation in scoreboard command.
/scoreboard players operation @s <Your Scoreboard> = @s randomfor example:
/function random:next/10
/scoreboard players operation @s killPoint = @s randomThe random number will create in range 1 to 10 and put into scoreboard killPoint instead. or adding point to your scoreboard by
/function random:next/20
/scoreboard players operation @s gold += @s randomThe random number will create in range 1 to 20 and add into scoreboard gold.


There are many more ways to use. Just try to apply to your problem.
