This statement could only ever be uttered by someone that has not tried to do this.
100x increase in any endeavor is extremely exceptional. It's as hard to do as turning $10,000 into $1,000,000.
The only thing having a larger starting amount helps with is that it opens up types of opportunities you did not have before that require greater starting capital and are outside the stock market. Those additional opportunities are as hard to capitalize on as the smaller opportunities that only require $10,000, especially since you need not only money but a lot of people with expertise that you can trust.
But within the stock market, a 100x return is something very few people in the market ever achieve.
The only place where having money clears some significant initial hurdles is probably getting to the first $10,000, maybe the first $100,000. This is a hurdle many have cleared in their lifetime and they still haven't succeeded in turning it into $1 million to $10 million, respectively.
