No, probably 10A or more - the current rating is not useful in a MOSFET as it applies to the thermal limit (liquid-cooled situation). You never want to run the device anything like that hot.
What you do is calculate the dissipation from the on-resistance and load current, and decide whether that's workable for your situation (perhaps you don't want to have to use a heatsink).
For instance a 10 milliohm on-resistance FET with 5A dissipates 5 * 5 * 0.01 = 0.25W which is OK without a heatsink.
An 80 milliohm FET with 8A would be 5W, required a medium-sized heatsink.
etc etc.
