Doesn't matter because you can customize it as you go, but it mostly gives you something to aim for. A lot of it comes down to what you pick along the way to suit your combat style, and the weapons/armor/spells you use.
Most people put decent points into stamina/endurance early, with whatever points in strength/dexterity/faith/intellect they need to use certain weapons/armor/spells they prefer.
Your stats will decide what you can use, and of that, how your style changes. So say you put a lot of points in faith - you can use different miracles, and it would give you bonuses to Divine weapons. You can also change your combat style based upon what gear you wear to compliment that. So you could be a "holy man" of sorts, but you could wear cloth and dodge a lot while casting spells - wear heavy armor and a shield and tank - or go with medium armor to give you enough defense and agility to survive, yet swing a nasty 2hander.
The game is ridiculously customizable.
