You should probably try iron bank instead, the chances to land a decent multipliers from normal spin is way higher than in Money Train
Is this just your observation or do you have any resources to find where we can enjoy bigger multipliers; if so, please link me 
.A 60$ bet, that's already quite big!
It all depends on luck. Sometimes you play on a slot with a few spins and directly get to the bonus rounds. In another moment, you can spin 100 times or more and don't get it.
I am following right now 'Ayezee' on youtube/twitch. He is making 25,000$ buys on a lot of slots and ended with (big) profits 13 of the 14 times he did it...
I believe you could always get lucky, there isn't a need to check others wins and think that they are lucky because we do not know what they did to get there, maybe they gambled 1000x more money to win this, maybe it was their first ever bet and they won, it is not an information we have.It all depends on luck.

However we should not feel envy for the other people because in gambling you could always get lucky, it is in the DNA of the gambling world, there is nothing you could do that would be different from these people because they click the same buttons you click and they just happened to get it now and you could happen to get it later who knows when your lucky would turn. I recently got to about 3k dollars from 100 dollars, then lost almost all, deposited another 50 bucks to keep playing and over time I reached back to 2.5k, I didn't chase it but just got super lucky, things happen both ways on gambling.
