Moomoo margin account risk level

Hi, I’ve recently opened a Moomoo account, deposited SGD and bought some SGX stocks.

When I went to view my “Account Details”, there is a “Risk Level” section at the bottom with the following headings:

1. Current state
2. Initial Margin
3. Margin-call Margin
4. Maintenance Margin.

Qn: Should I be concerned about the above if I always buy stocks with sufficient amount of cash in my account? Thank you!
