You might face more losses next time when you play the Plinko game again. Because the house will try to balance its edge in the long run. I play at low risk with 8 rows for wagering purposes. As a result, there were no opportunities for me to have a lucky session like you.
I really want to agree with you that in the long run its always the house that wins, but things dont work exactly like that under the hood. Just because you have been winning for too long or because you hit a long winning streak, doesnt mean you will suddenly start losing.
Yes, the casino always wins and thats a fact, but not in that way. You dont need to lose for the casino to win. What you need to understand is that someone else is paying for your wins. In other words, when you win, someone else is losing.
In my opinion, when people enter gambling, they need to look at things this way: they will have more losses than wins, which is why they should only bet amounts they can afford to lose. If they really want to beat the house in the long run, they need to be determined to the point that the day they hit a high multiplier, then on that day they should stop playing immediately and never play again. They should take their winnings and invest them in something in the real world. That's why I wouldn't advise anyone to keep playing with low multipliers.
Honestly, I think this way: we will all lose anyway in the long run. So, when we bet $10, we already have in mind that it's an amount with a low chance of not losing. Therefore, it's better for the person to bet $0.20 in each section and at a very high multiplier. If the person is lucky enough to win, they will win a lot of money, an amount that will change something in their life.
