Worst pack opening

Hello. I apologize in advance, I do not speak English. All you are reading now is google translate. And he doesn’t always translate correctly.
I share my statistics. I opened 162 packs, got 7 legendary cards. I think this is abnormal. There are very few epic cards, and only one epic, gold. Naturally, as an active player, I watch a lot of streamers, and on average I see statistics, 10 legend cards for 147 packs. Someone has 153, someone even has 120.
I.e. it turns out that I watch streams where people have good statistics, I make purchases, + spend more gold, but the result is much worse. I thought this was only done in online casinos. Blizzard, where are my legendary cards?

Friends, please answer without major grammatical errors. So that Google translator can translate correctly. Thanks.

Assuming you received your first Legendary in the first 10 packs, the ratio is 6 Legendary cards in 152 packs.
That’s an average of 25.333 packs per Legendary. That’s actually close to the expected average of 1 Legendary per 20 packs.
