If you purchase a bat pack, then you will receive all bats listed in the bat pack for the listed price, yes. This is a single bat however, not a bat pack.
The Adidas EQT X2 BBCOR Baseball Bat: X2 typically used at the high school and collegiate level. If you're player is in high school, this bat will be legal for use. If your player is playing in a league like AABC, Babe Ruth, Cal Ripken, Dixie Youth, Little League, & Pony then your player will want a USA bat.
Based off your height and weight I would recommend looking at a 33'' 30 for the Adidas EQT X2 BBCOR Baseball Bat: X2.
