so the best ability to play The slots is the availability of time and money, the tricks come later.

Yes, time is important since slots is a long game. With a decent bankroll, I can spend 7-8 hours in one session. Time flows differently in a slots game so you should schedule your session wisely.
But it is still unbelievable for me to get not even 1 single scatter in 150 spins. Never experienced such bad thing in my slot gambling journey for years. It is usual to get no free spins within 150spins, but not even single scatter? Still waiting the answer from ShowOff on which slot he experienced, even an extreme volatility slot is rare to get no single scatter within 150 spins.
Theoretically, I believe it can happen, but in reality, we rarely observe this thing. Perhaps ShowOff only exaggerates his bad luck. I think I had this no scatter session, but perhaps it was less than 100 spins. I didn't count, really. It's on games that only has scatters on line 2, 3, 4 or only on line 1 and 5.
