Welcome to [The World]
A RolePlaying Game.We'll get to making your character later for now lets explain some other stuff.

Well, your character will start off as level 1 and Have these stats
50/50 Hp 50/50 Mp
5-str 5-dex 5-int 5 Agi


Hp= Hit points for example say you got hit and it was a 5 damage attack and you had 40 hp you would subtract 5 from 40 and have 45/50 hp the 45/50 <----- the 50 is the total amount of hp you have and you can't have anymore hp until you level up
Mp= Magic points are mainly for spells same thing as hp you just subtract the cost say you used repth(healing spell) and it costs 25mp and you have 50/50 you would subtract it from the LEFT! side so you would then have 25/50 mp left.
Str-Determines how much certain classes physical attacks are str=strength
Dex-Determines how much certain classes hit with range attacks Dex= Dexterity
Int-Determines how much magic attacks hit.Int=Intelligence
Agi- Determines how much a certain class hits. Agi= Agility

You will have 5 points to distribute amongst Str,Dex,Int, and Agi.Each time you level up.
