Will the amperage increase when the batteries are connected in parallel?

Hello, help me deal with the following situation, because after searching the Internet I found a lot of disagreement in the next question. For example, I have 10 AA batteries of 1.5 Volts each. If I connect them in parallel, will only their total capacity increase or also the current strength? If the second is true, then how can the current increase if, according to Ohm’s law, I = U / R, and the voltage does not change with parallel connection, i.e. it will remain 1.5 V, which means that connect at least 10 batteries, at least 50 in parallel, the current strength at the same load will not change ??? Although many articles say that the current strength in parallel connection is summed up. Help to deal with this moment. Thanks in advance!

    When connecting the batteries in parallel, the voltage will be 1.5 V - that is, equal to the voltage of one element. One battery is designed for a specific load current, which can be connected to it. With a parallel connection, the current of all batteries is added up - that is, you can connect a larger load to them than to one element. In this case, the current strength means the amount of load that can be connected. For example, one battery can power one light bulb. If we connect five batteries in parallel, then these batteries can already supply 5 light bulbs. But it is not necessary to connect 5 bulbs to them. You can also connect one light bulb to them, it just works longer, as the total battery capacity will increase.
    The total battery capacity in this case is also added up. For example, one battery supplies one light bulb for an hour. If you connect 5 batteries in parallel, the total capacity will be 5 times higher, and the same lamp from the connected batteries will work 5 times longer - that is, 5 hours.
