Being lucky with some high multiplier bets but the manager gave us a warning about risk of betting with high multipliers. It's fair and straightly enough towards the risk and benefit when chasing big wins with high multipliers.
That is because there is a relationship between profitability and risk, not only in gambling, but in everything that has to do with money in general, which I would say is almost an economic law. If you play roulette on red or black the probability of winning is relatively high, 47.4% if it is American roulette, and you will win the same amount you bet, if you bet $100 you will win another $100. On the other hand, if you bet on a single number the probability, or the risk of losing your money, is much higher, since you only have a 2.6% chance of winning, but in general if you win you will be paid much more, about 35 times the bet, that is, if you bet $100 you will win $3,500.
In the example of slots it is the same, if you can get higher multipliers it is because you are more likely to lose your money.
And as I said, it does not only happen in gambling. Investing in bitcoin is safer than investing in an altcoin that has just been created. Maybe if you invest in the altcoin you make 100x or 1,000x but because the probability that the price goes to 0 and you are left with nothing is very high too. On the other hand if you invest in bitcoin you will not make a 100x but it is almost impossible that it will go to 0 in this next cycle.
