Is it wise to put all into FNCMX and FITLX

I am a college student, with a part time job. My income is not a lot but I figured it’s never too early to invest. I’ve learned about vanguard ETFs but don’t have enough principal for those. I have been using fidelity for a while (with roboadvisor and a small amount in self-managed stocks while learning), but have decided to move all of my roboadvisor money ($xxx) to ETF for better returns. I plan to split that amount into two portions (FNCMX and FITLX) and just add a small amount of money each time I have it.

On the side, I’ve also put $50 into ABML, IMPP, VLTA, and RPTX after some research.

Is this a reasonable strategy? Should I perhaps begin creating my portfolio of a range of large companies rather than ETF. I’m interested to learn and have some time on the side, but not a crazy lot. Thanks in advance!
