Gambling or Investing?

Hello! 18M and looking for advice about investing, especially with the psychology I should have with stocks.

I have 14k in a TFSA and already a little big of knowledge on investing. Lucky to have parents that are okay with me staying longer, plus money already saved up for school, which I intend to stay in for another 5ish years. With that safety net, I feel like I can afford RISK😈…

I’m also starting to read about investing before making any major decisions, would also like to see what everyone here might think of my stock choices for now.

Apple, Amazon, Microsoft. 3 of the MAG7 that hasn’t raised as much as the others

Adobe and Crowdstrike. That’s where the risk starts. Adobe feels undervalued for how much moat it has. For CRWD, cybersecurity will technically stay super relevant, it is losing money right not but not much. When it goes in the green, it should skyrocket right?

Mastercard, Walmart, Chevron, Goldman Sachs’s. Safe picks to balance out the risk. Thinking about potentially dropping some to go riskier and make the best of the time I have.

I’ll make sure to read every comment, your time is much appreciated!
