Not all investments result in profit. Sometimes you get good profit and on certain occasions, you will lose your money. I think not all low-price coins are good for investment. I have seen many analysts saying that SHIBA, PEPE, and DOGE are good coins for investments and some are even saying that SHIBA might touch 1$ in the future. If you buy a lot of cheap coins, chances are that only a few will give you profit if you are lucky enough.
The tokens and coins you've mentioned are meme coins, and they don't have a certain future which means that they are based on hype, if they get enough hype from the market, they will gain value, and if they don't, they will either stay sideways of die off slowly over time.
Apart from these, there are a lot of altcoins that have a low price when they are launched, however, a low price or a low market cap doesn't determine whether a coin or a project will be successful in the future. A project having a low price and also a low supply might manage to gain some value over time but only if the project is good and some people trade it when it's listed in big exchanges.
Altcoins in general are risky, and one needs to do thorough research before choosing any altcoin to invest their money in.
