why does late position let you play

i am also new to the game
please give me some explanation on that one
frink mid pairs meaning 22-77 or on the flop anyway if its 22-77 then he/she should be playing them. the implied odds on them are huge as long as you both have decent stacks. even if it is raised it is still a good call. how many NL $25 party player can lay down TT-AA with all unders?
example: NL $25 on party blinds .25/.50. you know he has AA and raises to $2 you have 22 and call $2. you hit a set 11 times so 11x$25 = 275.
88 times he/she misses you lose 88x2 = 164. maybe ~50 or so on a suck out or when they both hit sets. so its good to play them unless the AA makes a big raise pf which most of them slow play it anyway lol. for the times you miss, no set no bet as bonchkid so eloquently put it so you wont be losing anything extra.
