By doing the command:

/execute as @e[type=villager] run data merge entity @s {Gossips:[

]}

I would expect the villager to have good trades for everyone, And by doing the command:

/execute as @e[type=villager] run data modify entity @s Target set from entity @a[sort=nearest,limit=1]

I would expect it to be applied only to the nearest player.  This however is not the case. If I simply typed it wrong feel free to let me know.
