I already know that command to only allow host 192.168.122.107

Subnet mask tells you what part of IP address is the network and what part is the host address inside this network. Apparently in this case it is used for slightly different (although really the same) purpose: to specify a range of IPs.

Yeah man you can do whatever you wish! You can also assign a reservation in your DHCP server via MAC Address to give that one machine a /32 iirc

What is this

If you use 192.168.122.107/24 , you actually allow any IP from 192.168.122.1 until 192.168.122.254 to access your server

You should relearn networking. If you want to allow only single IP, the subnet is /32. If you put an IP and a subnet of /24 , the whole /24 range of that IP will be allowed
