Regardless of the average, you have a 75% chance to win at least 1 item, not a 100% chance.

it is bacuse of three spins granted >> 3 times chance
Read more carefully. I found a 13.67% chance to win a card on each spin, when it should've been 5% according to what I've heard. 3 times 13.67% is the 41% that I also mentioned for the chance to win a card after a match, or in 3 spins.
Actually math doesn't work like that. You cannot just add up the percentages.

Think about this. If I spin TWO times, and the possibility of winning a card with one spin is 50%, does that mean my chances of winning are 50%+50%=100%?
Yes it does.
No it doesn't.

Here are the possible results:

Loss + Loss
Win + Loss
Loss + Win
Win + Win

No wins = 25%
1 win = 50%
2 wins = 25%
