$begingroup$ I suspect they themselves don''t quite know what they mean by ''drawing'' current. However, a "load" is essentially a device to which power is delivered.Thus, increasing the load on, e.g, a motor, requires the motor to deliver more power and, assuming the voltage to the motor is (more or less) constant, this means an increase in current through the

This voltage difference drives current through the circuit, from one terminal to another, and back through the battery. As the current flows, the same amount of charge passes through both sides of the battery, ensuring equal current on both sides.
In a battery, current is the same on both sides because it forms a closed circuit. The battery’s internal chemical energy converts to electrical energy, generating a voltage difference between terminals. This voltage difference drives current through the circuit, from one terminal to another, and back through the battery.
Let's consider a simple example with two batteries connected in series. Battery A has a voltage of 6 volts and a current of 2 amps, while Battery B also has a voltage of 6 volts and a current of 2 amps. When connected in series, the total voltage would be 12 volts, and the total current would remain at 2 amps.
When somebody applies Kirchhoff Laws to the circuit consisting more than two batteries, the current leaving the battery is as same as entering the battery. I have no problem understanding the circuit consisting of only one battery due to charge conservation.
Batteries in parallel problems are often caused by incorrect wiring. When batteries are wired in parallel, the voltage of each battery is added together. If the positive terminal of one battery is connected to the negative terminal of another battery, the voltages will cancel each other out and no current will flow.
