if you take 1280 teams,

91 of them will win the league title
11* will win the champions league
10 will win the cup

So, they are sort of equal but less teams win the cup each season.

*out of 1280 teams, 4 out of every 14 (4/14 = .286) teams will qualify for the champions league which means there are 366 teams (1280 x .286) eligible for the champions league title. But only 1 out of every 32 eligible teams can win the title, so there are 11 (366/32) champions league winners.
