Basically, yes.
The vast majority of the time, splits accomplish very little in and of themselves. It used to be (back in the day when things weren't almost entirely electronic) that trading in round lots of 100 shares was preferred. Buying or selling something other than that (or a multiple of that), called an odd lot, usually incurred an extra premium on the commission because it required extra work on the part of the broker to match buyers and sellers. Thus, for people wanting to buy 100 shares, stock splits made it half as expensive to buy a stock. This meant that more people could buy the stock, and the price would go up.
But since round and odd lots trade under the same commissions these days, this incentive to split stocks is gone. (There are stocks like Berkshire Hathaway A where the share price is so high that a lot of people can't even afford to buy a single share, so a split would benefit there. Hence the creation of class B stock, which is still expensive. But those examples are very few and far between.)
The biggest positive to come from stock splits today is that it generally signals confidence in the company's future on the part of the management. If the management had concerns that the stock price might drop a significant amount, they probably wouldn't split it. Similarly, it possibly signals a feeling that the stock will continue to rise. But even this signals isn't universally accepted. Management does have inside information that could give them more insight than the average investor into the future of the stock, but they don't know all. Stock prices are notoriously fickle.
