Random (guest) devices connected to the router will still be allocated dynamically some IP address by its dhcp server, typically starting from 2 and incremented from there. Since most of your devices IP addresses start from the top it's unlikely there'll be clash, because any dynamically allocated IP address leases will soon expire.
Some routers can be told "only allocate these addresses" such as 1-100. That way you've reserved a block (101-254) that you can assign statically knowing the router won't collide with them.
