Why?

because you haven't learned to avoid them yet
get good

this is how you do it, dark souls fanboys

I just started playing 1v1 yesterday.

this changes nothing

there are ways to avoid projectiles--just experiment

you can usually dissipate weaker projectiles simply by punching it

Ok.

or you could pick up a character like fox, who has a reflector (down+b)

and then projectiles will never be a problem again

Falco or Fox.

Are they the only two characters who have reflectors?

oh no, there's all sorts

mario and dr. mario can use their capes (side+b) to reflect
pit and dark pit have mirrors (down+b)
palutena has a mirror (can't remember the motion)
mewtwo can use his side+b

and while they're not reflectors, these characters can stuff projectiles as well:

mr. g&w can use his bucket (down+b) to store projectiles and spit them all back at once
ness and lucas have their PSI magnets (down+b) making it so energy-based projectiles heal you
rosalina can deflect projectiles, but she can't send them back to your opponent, as far as i know

the only problem is that these characters can be difficult to use effectively

fox is simply the easiest one to use, in my opinion

How to beat projectile spammers:
1. Get close and put pressure
2. Read and punish rolls

Ok.

You can just roll through all the projectiles

True.

YEAHHHHHHHHHHH BOIIIIIIIIII

Shielding and Side stepping usually does the trick. Just be ready for your opponent to get more aggressive as you close the gap.
