is winning the cup in first season a big achievement

[-Robin]

I joined this game a few days ago and I am in round of 32 for the cup, I already think I won because theres only 2 people left in the cup that are actually real people and both of them lost their first leg and I won my first leg 5-1 today
am I get really lucky that I got drawn with bots or is it no big deal winning it in 1st level
ps the reason why I think I already won the cup is because my team is rated 17.4, 10.8 million value and no one in the cup is even close to my team, is this luck or is every server filled with bots ?
