What does the ball compression of a golf ball mean?

I bought a box of Taylor Made burner tp golf balls and on the side it says it has a 75 ball compression could someone explain what that means and if they are good for me- I have a slower swing speed.

In your opinion, What is the best golf ball for me?

I am 14 and a 7.3 handicap and hoping to lower my handicap. My swing speed with a 6-iron is 88 mph. I hit my driver anywhere from 260-290 yards. 3 Wood-245. 4 Wood-230. 3iron-210. 4iron-190. 5iron-175. 6iron-160. 7iron-150. 8iron-140. 9iron-130. PW-115. 50* Wedge-105. 56* Wedge-90. I spin the ball backwards on every shot up untill my 4 iron. I used Steel Stiff Men’s shafts with Cobra 3100ih golf clubs, Titleist 904 woods, and a Callaway X-460 Driver. What is the best ball for me?
Also to add, right now I use a Titleist ProV1 392. Is this the right ball for me?
