EVs and IVs in Competitive Battles?

Question

I've started playing Pokemon Y competitively online and I've noticed that I lose quite often...
I'm wondering if this has anything to do with EVs and IVs?
Do EVs and IVs matter in competitive battles?

Comments

Yes, almost all Players's pokemons are with EV training and Max IV.
ofc that if you don't have any pokemon with ev training you ill get some difficulty to win.

Answer 1

EVs and IVs are really important.

EVs
To explain EVs simply, for every 4 EVs in a stat you gain 1 point in that stat. The maximum amount of EVs you can have in a stat is 252. You can max out 2 stats and put the remaining 4 in another one.

So in total you have 508 useful EVs available(you actually have 510 but the last 2 don't make a difference).

IVs

IVs are a bit more complicated. They are like Pokemon genes. They determine your Pokemon's stats and cannot be changed unlike EVs.

HP IVs are calculated differently from the rest. These two formulas are used to calculate the IVs:

Aside from determining stats, they also determine what kind of hidden power your Pokemon will have.

>The last binary digit for each stat sets the move's Type, and the second-to-last digit sets the move's Power.
