Is Hacking from a Virtual Machine or Using Kali on It, Secure ?

I'm new to VMs and Kali, and since I downloaded it I had the questions (Am I safe? will my computer be affected? ) what I mean is: can't anyone gain access from the VM to the host system? or can someone track me somehow via the host system even if used vpn and macchanger on the VM? since kali as a VM connect to the internet via cable not wifi.
