Yup, true! I have been told even buying $50 dollars worth of Bitcoin, or even $10 worth of Bitcoin is good enough to get you started into Bitcoin.
Owning at least 1 BTC now would be ideal, and its not bad owning 0.1 either, is just that the earnings you might get is not even a lot. But every newbie should not think that way, instead, they should try to earn/buy Bitcoin slowly and saving up, and I bet that isn't impossible. It just takes time.
